浅谈剪重比指标在结构抗震中的应用

Discussion on the Application of Shear- Weight Ratio in the Earthquake of the Structure

剪重比是建筑抗震设计中的一项强制性指标,《建筑抗震设计规范》对其最低限值也有了强制性的规定,但是规范并没对这一指标作本质性的推导,也没说明当这一指标不符合要求时要采取的具体措施,以及剪重比与结构的自振周期、结构刚度之间的内在关系。现在就以上一些内容通过具体数据来对抗震规范中的剪重比作一些深入的讨论。

Shear- weight ratio is a compulsory provisions in seismic design of buildings. The minimum limit of its specification has also been mandatory required in ＂code of aseismic design of buildings＂,but it did not have an essential derivation on this indicator,and it did not express what specific measures we should take when this indicator do not meet the requirements,as well as internal relations with vibration periods,structural rigidity. Now this paper makes some in- depth discussion on the above content through specific data on shear- weight ratio of＂code of aseismic design of buildings＂.
