| Abstract: | In this paper, bassed on revered cycle loading tests on the two specimens of concrete structures with short shear wall and unbonded tendons prestressed slab, it analyzes the behavior of this concrete structure system under cyclic loading by finite element analysis. At first it studies mainly the bearing seismic capacity under different level stirrup, rate and beam stirrup in four top story knee joints for the concrete structure system. At last, it brings forward the quantity of level stirrup for top story knee joint. |
