An elevated reservoir is mostly used to store, liquid products like water, petroleum, and other types of chemicals, which require some static head to provide kinetic energy for flow. Except for the durability aspect, design load calculation of various reservoirs is similar regardless of the chemical aggressiveness. In general, water-retaining structures have been designed as crack-free structure to avoid any sort of outflow. As per the observation from the field, the overhead water tanks were designed continuously using the old Indian Standard codes (IS 3370: 1965 (Part 1 to 2), IS 1893: 1984 (Part 1) and IS 875: 1987 (Part 3)). In order to understand the variation in design due to amendments in Indian Standard (IS 3370: 2021 (Part-1 to 2), IS 1893: 2014 (Part-2), IS 875: 2015 (Part-3) in past few years, it is necessary to do comparative study of design of elevated reservoirs for different capacity. This study is an attempt to compare the design provisions based on different design philosophies i.e. WSM (IS: 3370 (1965) and LSM (IS: 3370 (2021). In this paper, variation in reinforcement quantity in different elements of double domed elevated reservoir has been estimated for 100 kL to 300 kL capacity for seismic zone-III and for wind speed 39 m/sec. A design program has been prepared for the design calculations of overhead water tanks using MS excel for different capacity and distinctive IS codal provisions. Comparison of results using different design philosophies has raised the need for retrofitting of various elements of existing water tanks.

The essence of the blast load relies on the factors such as explosive weight, standoff distance of the structure from the explosive, the location of the explosion concerning the structure, shape of the protective structure, and orientation of the structure relative to the explosion. The study provides an approach for calculating blast wave parameters according to IS 4991-1968 and UFC 3-340-02 and demonstrated by examples. It concludes that, in Indian Standard, only positive blast wave is considered but in UFC, both the positive as well as negative blast wave is taken into consideration. Also, there are significant differences in evaluating the parameters as per both standards.

The humans have been utilizing the resources for their sustenance since the birth of mankind. In fact, every living specie is dependent on the natural resources available to them for the nature to sustain their life on earth. As a result, the humans have reached on such a stage where they are standing on the verge of natural resources to extinct. However, the governments of various countries are taking serious actions in order to implement policies driven on the basis of circular economy to make sure the resources are utilized quite efficiently and also saved for the coming generations to come. It’s time for the common man to become aware about this serious issue of creating products of materials that cannot be reused or recycle. It is time we understand that the cycle of consumerism has to be not backed by production by the capitalists but rather using the resources and materials quite intelligently, smartly and in a limited manner to sustain living for the resent as well as for the generation to come. It’s time to understand the real meaning of sustainability and make it a part of the regime of this generation as mandatory prerequisite for the plans to be executed ahead. The need of the hour is to educate the people and bring the sustainable way of living in trend infusing it into the lifestyle of the people.

This study involves the wheel load stress at the different part (Interior, edge, corner) of the rigid pavement. The stresses and deflection at different part of the pavements are analyzed using ANSYS R18.0 modeling, which indicates the results of the deflection and stresses using Westergaard's equation and give FEM outputs in the form of presentation of the pavement. In this study finite element method is used for showing how that analysis is more viable in the analysis of the stresses at the different part of the pavement considering rigid pavement resting on elastic foundation subjected to static foundation.
