Abstract:
Authors analyzed strong column-weak beam design grarantee rates of reinforced concrete frames at the seismic rating of 1,2 and 3,fortification intensities were 7,8 degrees associated with various statistical characteristics of random variables in strong column-weak beam design feature function, eachly analyzed residential and office buildings' reliability index of strong column-weak beam of reinforced concrete frames in the seismic rating of 1,2 and 3,combined with a reliability index of strong column-weak beam in the seismic rating of 1,9 degreesfortification intensity areas, found out a reasonable range of super configuration percentage of reinforcement. Analysis results show that controlling super configuration percentage of reinforcement can ensure strong column-weak beam design of reinforced concrete frames. The conclusions provide the bases for further analyzing the reasonable range of the reliability index.
