Study of Performance Levels of Masonry Buildings Based on Damage
Performance levels in performance-based seismic design are affected by many factors. In this paper, based on the unclear division of the performance levels, finite element models of masonry buildings with windows of different sizes and different structural measures, according to damage constitutive equation of masonry in strain space and damage evolution equation , are built, which are analysed by the pushover analysis method. Stiffness change and damage evolution of masonry buildings under earthquake action are quantitatively described by the basic damage index and holistic damage index. In order to show their joint action on seismic performance of masonry buildings, the comprehensive evaluation coefficient is suggested to divide and evaluate performance levels of masonry buildings, which can evaluate overall seismic behavior of masonry buildings.
