In this paper the analysis is conducted to investigate the progressive collapse resistance of typical reinforced concrete(RC) multi-story frame structures, which are designed according to the China code for seismic design of buildings. The analysis results show that the progressive collapse resistance will be enhanced with the seismic fortification intensity increasing. The progressive collapse resistance of RC frame structures with low seismic fortification intensity are poor. This implies that as for RC frame structures with low seismic or non-seismic demand, close attention must be paid to continuity and ductility in order to prevent progressive collapse.

And Function

Dynamic load test is to measure the natural vibration characteristics of the bridge structure or the forced vibration characteristics under dynamic load, and to evaluate the driving performance, driving safety and comfort of the bridge through dynamic load test. In order to evaluate the stress state and working performance of a reinforced concrete box-ribbed arch bridge, the load test of the bridge is carried out. Dynamic load test is used to test the inherent fundamental frequency, damping ratio and impact coefficient of the bridge through pulsation test and sports car test. Through the experiment with the key parts of the stress (strain) and displacement load and other important data, through analysis and study, the comprehensive analysis of the phenomenon of calculation and test, a comprehensive performance evaluation structure and function whether meet the design requirements, to provide technical basis for the safety of the bridge operation, and provide the original material for the bridge maintenance and management in the future.
