Abstract

The current building seismic code provisions , seismic intensity of 8 degrees district includes basic design earthquake acceleration of 0.2g and 0.3g two districts . Specifications for these two districts , respectively, calculated earthquake , same basic seismic measures . 0.3g area 0.5 times larger than 0.2g earthquake , resulting in actual engineering specification states that the total height and number of layers of of 8 degrees district brick structure should not exceed 6 layer 18 meters , the frame structure The maximum applicable should not be more than 45 meters in height , \By multiple design analysis applicable height of 8 degrees 0.3g region brick structure and frame structure , draw the following conclusions : ( 1 ) select the the eight brick structure of the three types of layout structural design and seismic check using PKPM software analysis and comparison of the 8 degrees 0.2g areas and 8 degrees 0.3g brick structure in the applicable number of layers and the height difference , and to draw brick structure in the application of 8 degrees 0.3g region the number of layers and height should be higher than the 8 degrees 0.2g applicable , the number of layers and reduced the height of the ground floor and three meters . The proposed seismic codes alone to carry out the provisions of the applicable height and number of layers of brick and concrete structure of the of 8 degrees 0.3g region , the current specification \(2) selected the different layout frame structure , using PKPM Series software SATWE program spot ground conditions for the second category , the earthquake packet were two groups for each layout different layers the structural design . Variation member section size and the amount of steel with the growth in height and the number of layers ; compared with the amount of steel superstructure, and applicability initially analyzed spot ground conditions for the two types earthquake packet for the two groups , the applicable height of 8 degrees 0.3g regional framework structure should not be more than 30 meters . Also compared the differences in the amount of steel frame structure in 8 degrees 0.2g areas and 8 degrees 0.3g region .
