高烈度地震区侧煤仓结构选型及抗震性能分析

Discussion on Structure Selection and Seismic Behavior of Side Bunker in High-Intensity Seismic Areas

结合抗震设计规范要求,对位于抗震设防烈度8度、Ⅲ类场地土厂址上的某工程侧煤仓结构选型进行了探讨。通过分析,得出高烈度区侧煤仓宜选用型钢混凝土结构的结论。在充分发挥混凝土的高抗压性、高耐久性的同时,通过内置型钢提高其结构的抗震延性,从而改善原高强混凝土结构脆性破坏的特征。

In combination with the requirement of seismic design,the structure selection of side bunker is discussed in the 8 degree seismic intensity region with site Ⅲ.By comprehensively analyzing the performances of steel structure,it is found that steel reinforced concrete is conformable to the side bunker in a high-intensity seismic area.In the steel reinforced concrete structure,the high compressive strength and high durability of the concrete are well employed,and the shape steel is set to improve the seismic behavior of structure,avoiding the brittleness breakage of high strength concrete structure.
