［摘要］通過對嚴格按照相關規(guī)范設計的算例進行精細有限元動力時程分析，校驗了中國規(guī)范剪力墻結構能力調整措施的有效性。結果表明，現行規(guī)范的設計能夠滿足剪力墻結構的整體控制指標，能夠充分利用連梁耗散地震能量。但是，由于現行規(guī)范中未遵循地震力降低系數-位移延性系數關系的基本理論規(guī)律，未對各設防烈度區(qū)的結構采取嚴格程度相同或相近的抗震措施，從而使得設計受地震作用控制的7度（0.15g）結構破壞最為嚴重，抗震性能較弱；也正是由于隨抗震等級從一級到三級，采取的抗震措施逐漸減弱，致使連梁的延性需求呈現逐漸增大的趨勢；規(guī)范規(guī)定底部加強區(qū)高度對一、二級抗震等級顯得不足。規(guī)范的薄弱烈度區(qū)出現在按直覺似乎地震危險性偏小的7度（0.15g）區(qū)的抗震措施上，這需要引起足夠重視。

Abstract： The effectiveness of the measures of Chinese code for seismic design of buildings was verified by fine finite element dynamic time-history analysis of the relevant specification design examples. The results show that the design can meet the overall index of shear wall structure, can make full use of the beams to dissipate seismic energy. However, due to the basic theory of code does not follow the R-μ relationship, which leads the structure in intensity region 7 degrees (0.15g) to the most serious damaged, the seismic performance is weaker; with aseismic grade from 1st to 3rd, seismic measures gradually weakened, resulting in the increasing ductility demand of beams; with aseismic grade from 3rd to 1st, the height of the intensive area is insufficient in aseismic grade 1st and 2nd. The resistant measures of the 7 degree (0.15g) area are the most weak in the code, which needs to be paid enough attention.
Keywords： shear wall structure; failure mode; dynamic analysis; aseismic measure
