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

July'18



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.

The Impact Strength of Concrete with Nanomaterials at Elevated Temperatures

--Rakesh Kumar Choubey and B K Singh

An experimental investigation was carried out to determine the influence of concrete with nanoparticles such as nanocement, nanofly ash, nanometakaolin and nanosilica fumes under elevated temperatures. M30, M40 and M50 grades of concrete were cast. For each grade of concrete, 10%, 20% and 30% of cement were replaced with nanomaterials. The particle size of nanomaterials was determined using a Scanning Electron Microscope (SEM). The impact strength of concrete with nanomaterials under various elevated temperature (250 °C, 500 °C, 750 °C and 1000 °C) was found using impact testing apparatus. The impact strength was found to be least for concrete specimens with replacement of nanometakaolin. It was also found that the impact strength of M30 grade concrete specimens was low as compared to other grades of concrete (M40 and M50).

Influence of Elevated Temperature on Steel Fiber Reinforced High Strength SCC

--Vibhav Paranjape and V D Gundakalle

The paper studies partial replacement of river sand by M-Sand. River sand was partially replaced from 0% to 40% at an interval of 10% by M-Sand. With an increase in percentage of M-Sand, passing ability and flowability were decreased continuously. For strength and workability, 30% replacement of river sand by M-Sand was found to be optimum. Steel fibers were incorporated in the mix and varied in terms of volume fraction from 0.5% to 2.5% at an interval of 0.5%. Further, Rapid Chloride Penetration Test (RCPT) was also performed, and it showed that least penetration of chloride ions was observed at 2% volume fraction of steel fibers. All specimens showed very less penetration (<1000 Coulombs) values, subjected to elevated temperatures of 200 °C, 400 °C and 600 °C, for a duration of 2 h and tested for compressive strength. It was observed that all specimens suffered reduction in strength at elevated temperatures. The reduction in strength was least for SCC containing 2% volume fraction of steel fibers.

A Study on the Properties of Concrete with Coconut Fiber, Steel Fiber and Polypropylene Fiber

--B Siva Prasad and B Bhargav Kumar

The paper describes the enhancement in the strength of the conventional concrete by the addition of fibers. Coconut fibers, steel fibers and polypropylene fibers were used in the study. For all fibers, at optimum values, compressive strength increased for coconut fiber 5.5% and 7.2%, for steel fiber 2.5% and 9.5%, and for polypropylene fiber 4% and 6%. Split tensile strength increased for coconut fiber by 11.5% and 13.6%, for steel fiber 15% and 17.5% and polypropylene fiber 10% and 11%. Flexural strength increased for coconut fiber by 15.8% and 17%, for steel fiber 19% and 23%, and for polypropylene fiber 14% and 15.5% for M30 and M60 grades of concretes respectively. Durability tests like acid attack and alkaline attack were conducted on concrete with and without fibers. The results indicated a loss in all the strength parameters in varying percentages.

Shear Cracking Behavior in RCC Beams with Shear Reinforcement Using ANSYS Software: A Study

-- Shoaib M Hanagi and Kiran M Malipatil

Shear reinforcement plays an important role in the shear resisting capacity of the beam. It is necessary to study the effects of shear cracking behavior in the Reinforced Cement Concrete (RCC) beams. Various efforts have been put forth to study the effects of cracking and crack control in RCC elements. An analytical study was done on three RCC beams (A1, A2 and B1) using ANSYS 15.0 software and various parameters, such as shear span to depth ratio, stirrup configuration, crack patterns and load required for first crack initiation, were studied. Beams with unsymmetrical shear spans were prepared to study the effect of shear span to depth ratio; the depths of beams varied from 200 mm to 350 mm (ANSYS software). The effect of shear configuration is also studied where the beam is designed in such a way that right and left shear spans were spaced at 100 mm and 200 mm, respectively. Load required for first crack is calculated numerically and compared with the results obtained in ANSYS software. The crack patterns obtained in ANSYS software were compared with earlier works. Stress intensity factor for beams was obtained from ANSYS software.

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.
