In India, the modular precast construction sector, light gauge steel or commonly known as cold-formed steel and precast Ferrocement composite structures are gaining attention. This composite construction is a sustainable way of construction, leaving a low carbon footprint, as compared to conventional RCC construction. It enables fast construction with lower overheads, such as material transportation, labor cost, and amazing speed of construction thus making it an overall cost effective technology. The technology for typical G+5 residential building made of precast ferrocement panels combined with light gauge steel composite structure have been established. It claims to offer the practically enhanced solution to substitute the conventional RCC structure. Once structural performance is established, it is important to establish the thermal performance of this innovative construction technology for residential use purpose. This article represents the laboratory prototype study of residential space subjected to temperature variation, which may affect the comfort of the dwellers, energy requirement for maintaining working temperature for the building. Analytical and experimental approach establishes the thermal response of this precast composite construction technology and supports its futuristic development.

This study contains four models of RC Building of regular, mass irregular, stiffness irregular and soft storey. The peak responses of irregular building models are compared with Peak responses of regular building model. This building model contains ten stories modeled as shear type lumped mass system with single degrees of freedom at each floor level. The governing equation of motion is solved using Numark's method and is solved using coding in MATLAB software. From numerical results it is stated that peak responses of soft storey model gives better control over structural responses under various earthquakes except in some models.

Concrete is one the most extensively used construction material all over the world. Many scientists and researchers are in quest for developing alternate construction material that are environment friendly and contribute towards sustainable development. Huge amount of rubber tyres waste is being generating day by day which creates the disposal problem and has many environmental issues. As this scrap rubber waste is an elastic material having less specific gravity, energy absorbent material can be used as a replacement material for obtaining light weight concrete. In present study the modified concrete is prepared by replacing coarse aggregates in concrete with rubber aggregates by varying the replacement proportion from 0% to 20% with increment of 5%. The elastic properties are determined from concrete cubes. 3 cubes for each percentage of replacement are casted and tested after 28 th days of curing. Method of initial functions is used for the analysis of beams. The Method of initial functions (MIF) is an analytical method of elasticity theory from which stresses and displacement can be determined. This attempt of replacing the coarse aggregates with rubber aggregates will save the natural aggregates, reduces weight of structure and also helps achieve sustainability.
