Analytical Fragility Curves for Seismic Design of Glass Systems Based on Cloud Analysis

Given the growing spread of glass as a construction material, knowledge structural response must be ensured, especially under dynamic accidental loads. In this regard, an increasingly popular method to probabilistically characterize seismic given structure is based on use “fragility” or “seismic vulnerability” curves. Most existing applications, however, typically refer and members composed traditional building materials. The present study extends adapts such calculation innovative systems, which are characterized by specific material properties expected damage mechanisms, restraint details, features. Suitable Engineering Demand Parameters (EDPs) for design thus required. paper, major advantage represented Cloud Analysis in Cornell’s reliability method, assessment two different case-study systems. known represent simple immediate tool analytically investigate (glass) taking into account variations motions uncertainties parameters. Such exploited means detailed three-dimensional (3D) Finite Element (FE) numerical models non-linear analyses (ABAQUS/Standard). Critical issues typical failure mechanisms in-plane seismically loaded systems discussed. validity reference EDPs addressed examined solutions. Based broad investigation (60 records total), fragility curves developed from parametric results, so support multi-hazard performance-based (PBD) procedure.
