Abstract:
In order to study the Seismic damage mechanism.Based on the field investigation,it was found that the seismic damages of adobe-timber structures are collapse,partial collapse,cracking on walls,damage to timber parts,frame structure occured collapse, the damage to the beams and columns is rare and light, and the seismic damage mainly occurred in infilled walls.Masonry structures occured partial collapse,the joints of bottom frame structures were seriously damaged,shear damage to walls.The result shows that adobe-timber structures exist vertical rigidity irregular,plane rigidity irregular,poor integrity of wall,etc.Frame structures exit the consrtuction quality problem like lack of tie bar,low reinforcement ratio in columns and poor quality of concret,ect.Masonry structures also exit construction quality problems,such as low mortar strength,lack of seismic measures,etc.At the end of this article,some suggestions about the buliding defects are provided in order to provide ideas for reinforcement and reconstruction.
