This paper examines how the ANSYS software is used to conduct structural analysis of a multistorey building, which uses shear walls. Shear walls play a significant role in developing the lateral stability and stiffness as well as seismic and wind resistance of a structure. The effect of shear walls on the structural performance was assessed by modelling and structural analysis of G+10 reinforced concrete frame with and without shear walls. Lateral displacement, storey drift and stress distribution were the parameters under study. These shear walls led to large reductions in the deflections lateral and stability improved. The results prove that shear walls are significant to enhance the general safety and performance of tall buildings exposed to horizontal forces.

In this paper, the mechanical and the durability properties of concrete that partially replaced some amount of rubber have been compared. Waste tire rubber which was ground into fine aggregates replaced natural aggregates at various levels of volumes. Important properties such as water absorption, workability, tensile strength and compressive strength were determined. As per the findings, incorporation of more rubber enhances durability and impact resistance due to an increase in water permeability and fracture resistance, yet the compressive and tensile strength is reduced since rubber is not so stiff. The replacement was sensible and balanced in terms of both strength and sustainability. This study brings to the fore the possibilities of rubberized concrete as an eco-friendly construction material that serves to aid waste management alongside ensuring competency in terms of structural performance when used in non-load-bearing capacity.

This experiment is an investigation into using marble dust as a replacement of cement to some extent in polyethylene fibre-reinforced concrete (PFRC). One of the by-products of the marble industry called marble dust has an eco-friendly alternative that can be used in reducing the usage of cement and make concrete more sustainable. In order to determine the effect of the varying percentages of the marble dust (5%, 10%, and 15%) on the mechanical properties of the PFRC mix such as the compressive strength, tensile strength, and durability, different proportions of the marble dust were added to the PFRC commercially available mix and maintained at a fixed ratio of 6:1. There is an added resistance to crack and increased toughness by adding polyethylene fibre, and the marble dust has an influence on workability and strength development. The outcomes indicate that subbing parts of the marble dust up to 10 percent enhances strength without compromising on the fibre efficiency. The current research instigates the sustainability in construction, waste minimisation through the combination of industrial waste coupled with advanced fibre reinforcing technologies to produce lightweight concrete solutions that are environmentally friendly and durable.
