RELIABILITY ANALYSIS OF MULTI-STORIED BUILDING SUBJECTED TO WIND LOAD

Abstract

The reliability-based analysis of engineering structures is a crucial aspect of their design, evaluation, and maintenance. Reliability-based analysis focuses on assessing the probability of failure and ensuring the safety and performance of structures under varying operating conditions and uncertainties. It involves accounting for uncertainties related to material properties, loads, environmental factors, and modeling assumptions. The analysis process typically begins by establishing a mathematical model that accurately represents the structural behavior and its response to applied loads and environmental influences. Probabilistic methods like the First Order Reliability Method (FORM) or Monte Carlo simulation are commonly employed to quantify reliability and estimate the probability of failure. Several key factors are considered in reliability-based analysis, including the selection of appropriate probability distributions for input variables, the definition of failure criteria, and the consideration of aging and deterioration effects over the structure's service life. Reliability indices, such as the probability of failure or safety margin, are calculated to assess the level of reliability and evaluate structural performance. The outcomes of reliability-based analysis support decision-making processes by enabling engineers to optimize designs, determine maintenance requirements, and ensure the safety and reliability of engineering structures. This systematic approach offers a framework to account for uncertainties and manage risks associated with structural performance.
