  5. Based on the investigation of resident houses in taishun which was destroyed by shanxi reservoir earthquake and the site inspection of the destruction of building near epicenter, it is pointed out that the reason for severe seismic damage is that masonry - concrete structures built in recent years did not obey the rule of the code for seismic design of buildings [ 1 ], which mainly contains three aspects, first, the construction of wall was not consistent with the code, second, the design of structure was not reasonable, last, the site selection of base foundation was not good enough
