A Comparative Evaluation of a 13-story G+ Building with a Soft Storey, Using Pushover Analysis, with a Focus on the Impact of Different Placement of Shear Walls
Abstract: Asymmetrical structures with varying degrees of irregularity have proven to be a significant factor in causing collapses, damage to property, and injury during earthquakes. Despite extensive research on asymmetric buildings, there are currently no established guidelines for multi-story structures of this type. A soft storey, also known as a weak storey, is a level in a structure with insufficient rigidity or ductility to sustain earthquake-induced damage Pushover analysis has been …

Study on the Response of Strengthening Strategies for Masonry-infilled Open Ground Storey Framed Building
Abstract: The strengthening of reinforced concrete (RC) frame buildings with masonry infill wall and with open ground storey is a very timely and significant topic because of the poor performance against seismic action. The absence of infill walls in the ground storey makes the ground storey less stiff and weaker than the all upper storys which results in a poor performance against lateral loads. Soft storey mechanism prevails in these cases …

Behaviour of Irregular Concrete Buildings under Seismic Forces
Abstract: The study of irregularities in a building is a fundamental parameter controlling the seismic response of buildings. From the past history of earthquakes, it is evident that the use of improper structural configurationswith plan irregularities and soft storeys has decisive effects on the seismic performance of buildings. The buildings with abrupt changes in storey stiffness have uneven lateral force distribution along the height, whichis likely to locally induce stress concentration. …

The Influence of Soil Types on the Performance of the Building Frames: A Dynamic Analysis
Abstract: The dynamic response of the building structure is to a large extent dependent on the nature of the supporting soil. Soil stiffness and damping metrics fluctuation can cause significant tension in the behaviour of building skeleton when exposed to dynamic loads such as earthquake or wind. This research aims to evaluate how different soil conditions namely hard, medium, and soft soils impact the seismic performance of building frames under dynamic …
