Alignment of Wind Reliability Analysis with Code-Based Equivalent Static Wind Load Methods
This project aimed to first identify the underlying reasons why wind demands estimated through wind time history analysis have been seen on occasion to exceed demand envelopes estimated from equivalent static wind loads (ESWLs) and secondly to uncover the reasons why initial reliability studies have suggested that there is a discrepancy between the reliabilities obtained from systems designed to comply with current load and resistance factor design (LRFD) procedures for steel and reinforced concrete main wind force resisting systems (MWFRS) and the target reliabilities indicated in Table 1.3-1 of ASCE 7-22.
