| 摘 要： | 利用我国现行抗震规范，直接根据结构的底层层间目标位移反向求取结构的底层层间屈服剪力；给出了该屈服剪力与结构基底剪力之比的数学表达式，初步分析了影响该比值的主要因素及其影响规律。在此基础上，提出了一种新的直接基于位移的结构抗震设计方法。最后，通过算例分析初步考察了该方法的可行性。

| Abstract: | Using the seismic design code of China, the yield shear force in the first storey of a structure can be obtained according to the target interstorey drift in the same storey. The ratio of the yield shear force to the base shear force of the structure is formulated, and the effect of main factors on the ratio is analyzed. Then, a new direct displacement-based seismic design method for RC structures is proposed. Finally, numerical analysis is conducted and the feasibility of the proposed method is validated primarily. |
