Abstract: Wall and tie column shear strength of every floor in masonry buildings as indicators of earthquake-resistant capacity, the evaluation criteria of the indicators was obtained based on the earthquake damage analysis on the 72 multi-storey masonry buildings in Dujiangyan and Hanwang areas. Based on these tests, a rapid seismic evaluation method of masonry buildings was proposed, this method can assess the degree of earthquake damage for the masonry structure under the level of seismic intensity directly. The application of the method is introduced by analyzing the earthquake damage of a masonry building in Wenchuan earthquake. The results show that the method can evaluate the aseismic performance for masonry buildings, and can assess the degree of earthquake damage additionally.

Abstract: The stair is the vertical transport hinge among stories, it becomes a very important component. the stair is seriously damaged in Wenchuan earthquake, and it failed to perform the role for person escaping in case of emergency. a reinforced concrete frame structure with plate stairs as an example, the finite analysis is used. Calculation result shows that plate stairs have a great influence on earthquake resistant behavior of the structure. Designing without the plate staircase in consideration would lead to structural weakness in some columns and cause seriously damage under earthquake and affect the safety of structure.
