( China Aeronautical Project and Design Institute, Beijing 100120, China)Abstract: The 5.12 Wenchuan earthquake result in serious destructions. From analysis on seismic damage of buildings, some suggestions on seismic fortification measures are put forward: to important buildings, multi - lines defence should be set and pure frames should be used less. When frame structures are checked following "strong column - weak beam", the strengthen effect that the cast - in - situ slab, reinforcing steel bar, compressed reinforcing steel bar to frames should be considered. When the curb walls and partitions are arranged in frames, the disadvantage should be considered. The wind columns of high gable in single - story mill buildings should be considered and in the meantime sudden change stiffness in up and down columns should be avoided. The work plane in single - story mill buildings should be parted away or connected to the column basing on the fact case. If connecting the two components, the seismic fortification check should be camed out carefully and proper constructional measures can be adopted. Columns without foundation should be reduced when part structures project the roof. In frame structures, staircase beams should be set close stirrups and waist bars in the mid - span; between stair plane slabs and end walls, gaps should be set; displacement between structural columns should be shorter, when the structural columns are set in the brickwork partitions of the staircases.
