Investigation of Seismic Pounding Effect on Symmetric 10 Storey Reinforced Concrete Buildings Using SAP2000
Abstract: ABSTRACT Earthquakes have historically been responsible for significant structural failures, often resulting in substantial economic losses and endangering human lives. One notable failure mechanism observed during seismic activity is seismic pounding, which occurs when adjacent buildings collide due to insufficient separation gaps. This phenomenon is particularly concerning in densely populated urban areas where space constraints often prevent the provision of adequate clearances between structures. Such impacts can lead to severe …

Cross Sectional Area of Column
Abstract: Abstract In structural engineering, columns play a critical role in transferring loads from beams to thefoundation. The load applied on a beam is transmitted to the column, resulting in an upward reactiveforce. This upward pressure necessitates the determination of the column’s cross-sectional area basedon direct stress analysis to ensure that the structure can safely bear the imposed loads. Additionally,an end moment develops at the joint between the beam and the …

A Comparative Evaluation of Geopolymer, Conventional and GFRP Retrofitting Techniques in Augmenting Seismic Robustness of RC Structures
Abstract: Abstract The requirement of retrofitting an old existing structure, rendered structurally unsafe (based on its structural health assessment) is observed to be a major challenge faced by engineers as it necessitates comprehensive and complicated repair procedures. It was further seen that during earthquake, the main reason for failure of any structure was the failure of its beam column joints, thereby making it essential to strengthen them specifically. Until recently, the …

Effect of Environmental Parameters on Metal Corrosion in Soil Using Finite Element Method
Abstract: Deterioration of buried metal due to corrosive soil environment is a major issue worldwide. Although failure of buried metal due to corrosive soil is an old problem, yet such failures are still uncontrollable even with the application of advanced corrosion protection technologies. Therefore, understanding environmental parameters causing corrosion of buried metals are necessary. This research work reviews environmental parameters causing corrosion of buried metal in soils. These functional parameters include: …

A Model for Plastic-Hydrolytic Damage Bioresorbable Polymer Composites
Abstract: This paper explains and assesses a recently developed constitutive model for elastic-damage that may sustain plastic-hydrolytic damage. When a metallic material is subjected to plastic strain, voids and microcracks in the metal matrix start to form, develop, and merge. This is what causes ductilitydegradation in metals. Only a few of the many models that have been presented to depict ductile failure have done a thorough analysis of the entire damage …
