【 摘 要 】

The two models commonly used in response displacement method were introduced. And then, put forward a simplified response displacement method (SRDM) using new load-structure (NL-S) model. Based on the classical response displacement method (CRDM), SRDM simplified the earthquake action of input underground structures, and neglected some computations which are cumbersome and small. Finally, SRDM was verified by an example. In the calculation, the general analysis of SRDM was carried out by changing the following 3 aspects: soil properties, seismic wave type, PGA. The 3 methods of time history method (THM), CRDM and SRDM were used for calculation. The results of SRDM were compared with the results of the other two methods. The calculation results shows that the SRDM is the most convenient and suitable for practical engineering application, and its calculation precision is high.
