一、前言钢筋混凝土柱承式贮仓是冶金、煤炭、建材和电力系统常见的构筑物,它是典型的上重下轻、上刚下柔的鸡腿式结构。在海城和唐山地震中,位于8度以上烈度区的贮仓都遭受到程度不同的破坏,因此贮仓的抗震问题至关重要。对于钢筋混凝土柱承式贮仓,其纵向抗震,可以采用多种措施解决,但其横向抗震,由于工艺条件(如仓下设皮带运输机或过往车辆) 限制,不可能采用与纵向相同的措施,只能根据现有的结构形式挖掘其抗震潜力。为此,本文提出把赘余杆(仓下水平梁) 作为柱承式贮仓抗震“保险丝”的方法,即在设计时,把赘余杆按弱构件设计,使其在地震时,首先出现塑性铰,从而提高整个贮仓结构系统的延性耗能能力,减轻结构的震害。本文在总结已有研究成果 I. INTRODUCTION Reinforced concrete column-supported silos are common structures in metallurgy, coal, building materials and power systems. It is a typical chicken-legged structure with a lighter, lighter, and softer top. In the earthquakes of Haicheng and Tangshan, the silos located in the intensity zone above 8 degrees have suffered different degrees of damage, so the seismic problem of silos is of utmost importance. For a reinforced concrete pillar-supported silo, its longitudinal seismic resistance can be solved by various measures, but its lateral seismic resistance is not likely to be the same as that of the longitudinal direction due to the limitation of the process conditions (such as the belt conveyor under the warehouse or passing vehicles). The seismic potential of the structure can only be tapped based on the existing structure. For this reason, this paper proposes a method of using the squat rod (horizontal horizontal beam) as the seismic “fuse” of the pillar-supported silo, that is, designing the squash rod as a weak member so that it appears first in the earthquake. Plastic hinges, thereby increasing the ductile energy dissipation capacity of the entire silo structure system and reducing the structural damage. This article summarizes existing research results
