The IUP Journal of Structural Engineering
ISSN: 0974-6528
A ‘peer reviewed’ journal distributed by EBSCO and Proquest Database


Previous Issues

Structural engineering is usually considered as a specialty discipline within civil engineering, but can also be studied in its own right. It is the science and art of designing and making buildings, bridges, frameworks and other similar structures. It has taken a completely different path since the middle of the 20th century. It involves understanding the load-resisting properties of components such as beams, columns, walls, slabs, plates, arches, shells, catenaries, etc., and selecting, proportioning, and connecting different components of a structure to resist the forces and displacements without affecting the safety of the structure. Structural Engineers are responsible for using funds, structural elements and materials creatively and efficiently. In recognition of the growing importance of this branch of engineering, IUP has come up with a quarterly journal, The IUP Journal of Structural Engineering.

A Study on the Properties of Concrete with Steel Slag as Fine Aggregate and Marble Waste as Coarse Aggregate

--S Sugasini and G Srinivasan

In construction industry, concrete is the largest produced material compared to all other materials. Aggregates are the important constituents in concrete. The increase in demand for the ingredients of concrete is met by partial replacement with the waste materials obtained by means of various industries. Steel slag and marble waste are the waste products generated during the production of steel and marble, which are disposed in the form of landfills, causing an enormous amount of land pollution. Therefore, partial replacement of natural aggregates with steel slag and marble waste would lead to considerable environmental benefits which have been emphasized in this paper. Experiments were conducted and data required for mix design were obtained. M25 grade concrete is designed as per the Indian standard code. The water-cement ratio is maintained for this mix design as 0.51. The steel slag and marble wastes were properly cut down to the required size of fine and coarse aggregate respectively. Then the steel slag was mixed with the concrete as fine aggregate in the percentages of 20%, 30% and 40%. It was observed that 30% was the optimum percentage replacement of fine aggregate using steel slag. Then the specimens were casted using this 30% steel slag as fine aggregate with variable percentages of marble waste as 20%, 30% and 40% as coarse aggregate subjected to curing of 28 days, from which their strength and durability properties were determined. The determined properties were compared with that of the conventional concrete. Of the above percentage mixes, partial replacement of fine aggregate by 30% steel slag and partial replacement of coarse aggregate by 40% marble waste mix were found to be favorable.

Experimental and Analytical Investigation of PCC and RCC Beams Strengthened with CFRP and GFRP Laminates by ANSYS

--Ranjith P Tulajannanavar and Kiran M Malipatil

In the paper, an attempt has been made to know the behavior of plain and reinforced beams strengthened with different FRP laminates such as Carbon Fiber Reinforced Polymers (CFRP) and Glass Fiber Reinforced Polymers (GFRP), to calculate the load required for producing first crack in Reinforced Cement Concrete (RCC) beams and comparing it with experimentally and analytically, to increase the flexural strength of the structural members strengthened with different FRPs and to know the load carrying capacity and deflection of both Plain Cement Concrete (PCC) and RCC beams strengthened with GFRP and CFRP. The test specimens of size 700 mm in length, 150 mm in breadth and 150 mm in depth were cast according to the mix design. The CFRP and GFRP laminates were wrapped at the soffit (tension face) of both plain and RC beams. The results obtained for the load required at first crack was 24.9 kN theoretically, 33 kN experimentally and 39 kN analytically using ANSYS software. By laminating CFRP and GFRP sheets at the soffit of the PCC and RCC beams, the deflections were decreased as compared to only PCC and RCC beams when the flexural load was applied. The analytical and experimental results for PCC and RCC beams wrapped with GFRP and CFRP were compared with each other. The results showed that the PCC and RCC beams wrapped with CFRP at the soffit of the beams gave higher strength and lesser deflection compared to beams wrapped with GFRP.

Workability and Strength Study on Fiber Reinforced Geopolymer Concrete

--Kiran Kumar Narasimhan, B Damodhara Reddy and S Aruna Jyothy

Concerted efforts are on worldwide to minimize the greenhouse gas emission related to construction industry by developing environment-friendly concrete alternative to conventional concrete. The paper presents the development of Fly Ash (FA)/Ground Granulated Blast Furnace Slag (GGBFS)-based ambient cured fiber reinforced geopolymer concrete and its workability and strength characteristics with variation of binder proportion (FA and GGBFS) and superplasticizers. In the present study, Polycarboxylic (MasterPolyheed 8145 and MasterPolyheed 8146) and naphthalene (MasterRheobuild 918)-based superplasticizers were used to improve workability. Fluid-to-binder ratio was fixed as 0.6 and the ratio of sodium silicate-to-sodium hydroxide is taken as 2. The steel fiber was added to the mix in volume fraction of 1% by the volume of binder. The prepared geopolymer concrete is checked for the workability and specimens of size 150 mm × 150 mm × 150 mm were prepared. The impact of fineness of binder material is also studied. From test results, it is observed that polycarboxylic-based superplasticizer gave better workability and strength than naphthalene-based superplasticizer. Workability and the strength characteristics improved with the use of finer binder material. Further, FA:GGBFS ratio of 70:30 developed higher desired strength.

The Effect of Elevated Temperature on Polypropylene Fiber Reinforced Scc

-- Vinayak B Patil and V D Gundakalle

Concrete is an extensively used construction material across the globe. It must justify some primary characteristics such as workability, strength and durability. To achieve these characteristics, it is important to lay emphasis on mix design that yields the above-said characteristics along with conservation of energy and materials. Self-Compacting Concrete, also known as Self-Consolidating Concrete (SCC), has revolutionized construction industry with its special characteristics such as high fluidity, filling and passing abilities, strength and durability. In this paper, SCC of M30 grade was prepared with partially replaced M-sand using Nan-Su method of mix design. Polypropylene fibers were added in successive volume fractions of 0.05, 0.10 and 0.15% to the optimized mix (40% replacement of natural river sand by M-sand). Rapid Chloride Permeability Test (RCPT) was conducted for 28 days cured specimens to understand polypropylene fiber influence on durability characteristics. It is also of paramount importance to study the behavior of SCC at elevated temperatures. It is generally observed that strength and durability of SCC are reduced at higher temperatures. It becomes relevant in structures such as power plants, chimneys and runways. The reduction in strength for polypropylene fiber reinforced SCC with successive increment of temperature from 200 °C to 600 °C was studied.

Drift Control in Tall Buildings Using Claddings

-- C M Ravi Kumar, H R Vinay and D M Anusha

The stiffening effect of non-structural elements in a building has been recognized for many years, but it has generally been neglected in design procedures due to lack of understanding of the interaction between these elements and the building’s primary structure. Cladding items are usually unaccounted for in contributing to the lateral stiffness of a building structure. The non-structural items, which are neglected, will contribute to a lesser degree in controlling the drift, especially in tall buildings. The paper presents the interaction of the primary moment resisting frame with grid panel cladding system.

Automated Teller Machines (ATMs): The Changing Face of Banking in India

Bank Management
Information and communication technology has changed the way in which banks provide services to its customers. These days the customers are able to perform their routine banking transactions without even entering the bank premises. ATM is one such development in recent years, which provides remote banking services all over the world, including India. This paper analyzes the development of this self-service banking in India based on the secondary data.

The Information and Communication Technology (ICT) is playing a very important role in the progress and advancement in almost all walks of life. The deregulated environment has provided an opportunity to restructure the means and methods of delivery of services in many areas, including the banking sector. The ICT has been a focused issue in the past two decades in Indian banking. In fact, ICTs are enabling the banks to change the way in which they are functioning. Improved customer service has become very important for the very survival and growth of banking sector in the reforms era. The technological advancements, deregulations, and intense competition due to the entry of private sector and foreign banks have altered the face of banking from one of mere intermediation to one of provider of quick, efficient and customer-friendly services. With the introduction and adoption of ICT in the banking sector, the customers are fast moving away from the traditional branch banking system to the convenient and comfort of virtual banking. The most important virtual banking services are phone banking, mobile banking, Internet banking and ATM banking. These electronic channels have enhanced the delivery of banking services accurately and efficiently to the customers. The ATMs are an important part of a bank’s alternative channel to reach the customers, to showcase products and services and to create brand awareness. This is reflected in the increase in the number of ATMs all over the world. ATM is one of the most widely used remote banking services all over the world, including India. This paper analyzes the growth of ATMs of different bank groups in India.
International Scenario

If ATMs are largely available over geographically dispersed areas, the benefit from using an ATM will increase as customers will be able to access their bank accounts from any geographic location. This would imply that the value of an ATM network increases with the number of available ATM locations, and the value of a bank network to a customer will be determined in part by the final network size of the banking system. The statistical information on the growth of branches and ATM network in select countries.

Indian Scenario

The financial services industry in India has witnessed a phenomenal growth, diversification and specialization since the initiation of financial sector reforms in 1991. Greater customer orientation is the only way to retain customer loyalty and withstand competition in the liberalized world. In a market-driven strategy of development, customer preference is of paramount importance in any economy. Gone are the days when customers used to come to the doorsteps of banks. Now the banks are required to chase the customers; only those banks which are customercentric and extremely focused on the needs of their clients can succeed in their business today.
