摘要
介绍2008年汶川大地震中框架结构的几种典型破坏特征,分析了包括短柱破坏效应、剪切效应、剪压破坏、压屈破坏、弯剪破坏、梁柱塑性铰、钢筋锚固不足破坏、混凝土酥碎破坏等震害特征,由此引发对框架结构抗震设计的思考。
This article introduced that frame structure has produced several typical characteristics of the destruction in the Wenchuan earthquake.Several typical characteristics of the destruction are analyzed,including the effect of undermining short column,shear effect,cutting pressure destruction,curved shear destruction,plastic hinge beams,steel anchor less than damage,broken concrete crisp,and other forms of damage,arising from the seismic design of the frame structure of thinking.
