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 Rheological Behavior of Fiber-Reinforced Self-Compacting Geopolymer Concrete: A Microstructural Analysis

--Shweta Bajakke, Komal Kattimani and G S Manjunath

Considering the need for developing an alternative construction material, the paper discusses the feasibility of alkali-activated Self-Compacting Geopolymer Concrete (SCGPC). The paper also presents the rheological behavior of fiber-reinforced SCGPC under the effect of steel fibers, dosage of SP and effect of extra water. Fluid-Binder (F/B) ratio of 0.6 with 1% of steel fibers with different dosages of superplasticizer, i.e., Glenium SKY 8630, was considered. The flow characteristics and compressive strength of the samples were studied. The results showed that with 6% and 5% of SP and 5% of extra water content, the mix was satisfying, the flowability properties and the compressive strength were maximum among all other mix proportions.

Fine Aggregate Replacement with China Clay-Based Concrete: A Strength and Durability Study

--J Saravanan and M Sabarirajan

The utilization of industrial and agricultural waste produced by industrial process has been the focus of waste reduction research for economical, environmental and technical reasons. This is because over 300 million tons of industrial waste is being produced per annum by agricultural and industrial processes in India. The problem from continuous technological and industrial development is the disposal of waste material. With the increase in demand for construction materials, there is a strong need to utilize alternative materials for sustainable development. Advancements in technology not only help in improving human comforts but also harm the environment. The use of china clay industrial waste aggregate in construction industry has become popular and safe now. At present, construction industry is in need of finding a cost-effective material to enhance the strength of concrete. In this paper, the effect of china clay waste and the chemical admixture (superflo) on concrete has been investigated. Natural aggregate was replaced with china clay industrial waste in different percentages, namely, 10, 20, 30, 40 and 50. A comparison was made between the specimens of partially replaced fine aggregate and the same set of specimens admixed with superflo. The effect on mechanical properties and durability properties was reported.

Relative Performance of Multistoried RC Buildings with Reduced Wall Densities

--P Markandeya Raju, S S Bhanu Sai Kumar and M Pavan Kumar

The advantage of adopting wall panels with lighter densities as precast wall panels (being developed in the recent past) needs to be assessed from the safety and serviceability point of view under loading. The paper presents a comparative analysis of multistoried buildings with reduced wall densities against ordinary brick walls. The type of building being considered for analysis is a G+5 RCC framed structure for residential usage. It was observed from the results that the final carpet area of the building increased when the panels were used in place of walls. With the decrease in the density of wall, no appreciable change in the volume of concrete was observed, but the savings in steel got reduced.

Performance Evaluation of RC Haunch Beam Frame with Shear Wall

-- Pallavi K Naik and Manjunath M

Beams are the major structural elements that carry and transfer the loads and are designed for bending and shear. Prismatic beams having uniform cross-section are commonly used for short and medium spans, whereas haunched beams are non-prismatic with varying cross-section. Shear wall structural systems are used to increase the stiffness of the structure to resist the lateral loads acting on a structure. The paper considers a 25-storey rigid frame structure and compares the performance of prismatic beams and haunched beams. Also, a comparative study of haunched beam frame with shear wall and without shear wall is made. The structure is analyzed for earthquake loads by both linear and nonlinear analysis using ETABS2015. Linear analysis includes both equivalent static method and dynamic response spectrum method. Nonlinear analysis is performed by pushover analysis. On the basis of the structural parameters studied, the general conclusion is that haunched beams provide more efficient use of concrete and steel reinforcement and reduces the weight of the structure.

Inelastic Analysis of Reinforced Concrete Frames

-- Jaiswal U N and Mohd. Zameeruddin

Buildings designed in accordance with the present seismic codes sustained large damages or collapsed during strong earthquakes, raise the question about the adequacy of seismic codes. This experience has forced the engineers engaged in design practice to focus on the predictive methods of design with predefined performance objectives. The Performance-Based Seismic Design (PBSD) has emerged as the best alternative that addresses multiple-level structural performances for the stated set of imposed seismic demands. This paper focuses on the assessment of the seismic performance of gravity-based design structure subjected to various lateral load patterns. Fourteen example MRFs designed as per IS: 456 (2000), IS: 1893 (2002), and IS: 13920 (1993), were subjected to the displacement-controlled pushover analysis. This example MRFs represent low-rise structures, located in seismic zone V, on the medium soil type with importance factor equals to 1. The parametric study includes: base shear, storey displacement, inter-storey drift and plastic hinge mechanism. Based on the study, a damage indicator is proposed which gives a measure of energy dissipated by the MRFs.

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.
