摘　　要：介绍了内藏钢板支撑剪力墙这种新型抗侧力支撑体系的特点及性能,通过对其屈服前刚度的有限元分析,并结合试验资料对比分析,对《高层民用建筑钢结构技术规程》(JGJ 99-98)附录中内藏钢板支撑剪力墙构件屈服前刚度计算公式进行了验证,通过回归分析,提出了内藏钢板支撑剪力墙构件屈服前刚度的修正计算公式,可为进一步的研究和规程修订提供参考。The characteristics and performance of steel plate brace precasted in shear wall are introduced,which is a new type of lateral force resisting brace system.By finite element analysis of non-yielded stiffness VS experiment data,non-yielded stiffness formula of steel plate brace precasted in shear wall in the Appendix of 'Technical Specification for Steel Structure of Tall Buildings'(JGJ 99-98) is tested.By linear regression analysis,the modified formula is concluded,which provides later research and the being-revised specification with reference.
