Research on Side Resistance of Prefabricated Precast Concrete Wall
In order to study the lateral resistance of prefabricated precast concrete walls,the effects of axial compression ratio on the bearing capacity,stiffness and energy consumption coefficient of prefabricated precast concrete walls were analyzed by means of test and virtual simulation.The results show that the skeleton curves are S-shaped under all axial compression ratios.With the increase of axial compression ratio,the skeleton curve appears a decreasing stage in the later stage.The lateral stiffness of prefabricated precast concrete walls with axial compression ratio decreases rapidly at first and then becomes stable with the increase of displacement Angle.Under the same displacement Angle,the greater the axial compression ratio is,the greater the lateral stiffness is.With the increase of the interlayer displacement Angle,the energy consumption coefficient decreases rapidly at first and then remains stable.The axial compression ratio has no obvious effect on the energy consumption coefficient and the evolution law of the interlayer displacement Angle.
