| Abstract: | By adopting nonlinear finite element analysis method,an all course analysis of the frame′s forced performance as a result of the foundation displacements after finishing the reinforcement of the power house is conducted.During the computation,some nonlinear characteristics that include cracking of concrete,yielding of reinforcing bar and appearance of plasticity hinge,and the secondary force character of steel encased concrete frame structure are taken into account.Finally,based on the calculation results,the effects and the safety degree after reinforcing the structure are analyzed and evaluated synthetically,some suggestions for the signs and the time that the power house is going to be in face of danger are also advanced.It can be applied to resisting and harnessing the slippage and predicting hazard for the power house. |
