Hence study on the response of tall buildings to earthquake loads is gaining significant importance. Outrigger tall buildings are one of the most common structural structures because they are simple to construct, cost-effective, and have significant lateral stiffness. Therefore, this research explores a structural outrigger system for high-rise buildings to analyze the output of a system by changing the place of outrigger positions. Dynamic research was performed in accordance with IS 1893, the response spectrum and time of California’s most recent earthquakes. The parameters discussed are lateral displacements, inter-storey drifts for static analysis, and base force, displacement, and spectral acceleration for dynamic analysis. From the analyzed results, it was found that an outrigger when located at H0/H=0.6 causes a maximum reduction in the lateral displacement. Hence outrigger located at H0/H=0.6 is the desired location to provide an outrigger in a structural system and could act as an initial economical prudent design solution in the construction of tall buildings with outriggers. Time history analysis shows that the reduction is maximum when the outrigger is located at H0/H=0.9 for LA03, H0/H=0.85 for LA06 H0/H=1.0 for LA14.</p> 2022-10-28T00:00:00+00:00 Copyright (c) 2022 The Asian Review of Civil Engineering Statistically Analyzing Fatal Accidents Pattern of Construction Activities in India 2023-01-12T06:29:04+00:00 Saket Patni <p>In construction activities, fatal accidents occur frequently due to inherently dangerous nature which accounts for around 38 fatal accidents every day as reported by leading news articles. The aim of the paper was to investigate the pattern of fatal accidents in India’s construction works by utilizing a statistical method known as frequency analysis. The methodology includes the collection of data on accidents published by government departments, private bodies, and journals related to this topic. The results were achieved by assessing the year, month, and state factors. The findings reveal that there are noticeable trends in fatal mishaps. These data can be used to offer guidance for corrective or preventive measures for occupational injuries. The pattern identified in this paper can be useful to guide the development of accident-preventative measures.</p> 2022-12-15T00:00:00+00:00 Copyright (c) 2022 The Asian Review of Civil Engineering Comparative Study of Wind Pressure Variations on Rectangular Buildings using Python Programming 2023-02-20T09:31:09+00:00 Pankaj Dumka Nitin Kumar Samaiya Sumit Gandhi Subas Dash Sumit Dubey Dhananjay R. Mishra <p>In this research article an attempt has been made to analyse the design wind pressure on the rectangular buildings using Python programming. For this purpose, design wind pressure is calculated and compared using IS 875 (Part 3) 1987 and the revised code IS 875 (Part 3) 2015. The concept have been applied to three different building heights i.e. 20, 40, and 60 m having same plan 1010 m<sup>2</sup>. It has been observed that the impact of wind pressure on the building rises with the building height along with the fact that the design wind pressures obtained from revised code show more pressures in comparison to the old one. Therefore, the design based on the revised code will be more close to the reality as it incorporates risk factor, directionality factor, area averaging factor, and combination factors. Also, the module developed for wind loads can be readily used by the researchers/designers for the better understanding of programming and the design loads.</p> 2022-12-15T00:00:00+00:00 Copyright (c) 2022 The Asian Review of Civil Engineering Hydrometallurgical Recovery of Copper Tailing Waste by Bioleaching at Hindustan Copper Limited, India 2023-02-23T10:11:40+00:00 Sandeep Kumar Shraddha Mishra Poonam Singh Anupam Singhal Sanjay Kumar Verma <p>The conventional methods of refining cannot be implemented for recovery of copper from tailing waste collected from Hindustan Copper Limited, Khetri, India as it contains low copper and higher iron along with other metals present. Hence bioleaching was tested as an alternative approach for the recovery of copper from the waste. The study investigated the feasibility of using a bioleaching process for the treatment of copper tailing waste. The XRD and ED-XRF analysis confirmed that the waste contained 0.13% w/w copper, which is present in different forms including chalcopyrite (CuFeS2). Shake flask studies optimized with tailing concentration, optimum temperature, and pH showed 94.03 % w/w recovery of copper at 2 % <em>w/v</em> waste concentration after 40 days of exposure at pH 2.0. The study was extended to a pilot-scale glass column filled with raw copper tailing mixed with <em>Acidithiobacillus ferrooxidans</em> at a flow rate of 3 L h-1. A recovery of 54.71% w/w of copper was obtained by this setup. The mix-proportion clay bricks were cast with the tailing waste after bioleaching. The bricks showed better compressive strength as compared to normal bricks. A pilot scale heap leaching study with 5 kg of tailing waste mixed with <em>Acidithiobacillus ferrooxidans</em> showed a 64.28% w/w copper tailing in 40 days.</p> 2022-12-15T00:00:00+00:00 Copyright (c) 2022 The Asian Review of Civil Engineering BIM Based Inventory Management in Construction of Residential Highrise Building in India 2023-03-11T04:16:36+00:00 Aditya Mahajan Anil Kumar Chilakapati <p>According to a study, construction materials account for more than 65 percent of a project's entire cost. Material Planning efficiency is critical to completing a project on scheduled time and on budget. This research paper focuses primarily on inventory control and materials planning using BIM process as this are the important pillars of material management. The S-curve analysis is used to determine how much the estimated materials cost differs from the market materials cost. Engineers and contractors are interviewed to determine the main reasons for this. Inventory management techniques such as ABC classification and economic order quantity (EOQ) analysis are performed. In most cases, S-curve analysis shows that actual material costs are greater than estimated material costs. BIM-based ABC and EOQ analyses are used to continuously maintain sufficient inventory, protect inventory materials from damage, reduce inventory costs, solve inventory problems, and maintain optimal inventory levels. A sensitivity check is applied to the results of the EOQ analysis. “The use of ABC classification and EOQ analysis can help to alleviate the stock-out of A class and B class materials that occur on building sites. Following the implementation of these easy inventory control strategies, the total inventory expenditure is reduced”.</p> 2022-12-15T00:00:00+00:00 Copyright (c) 2022 The Asian Review of Civil Engineering
