摘要
作为地下一种特殊的结构体系,地铁车站为长条形、大荷载和大跨度结构,通常可按二维断面框架结构计算并配筋。此时,框架墙板节点位置设计成为关键点,节点位置刚域作用或削峰处理,合理考虑轴压力的有利作用,能充分发挥钢筋混凝土性能,达到较好的经济效果。
As a special underground structural system,subway stations are long,large-load and long-span structures,which can usually be calculated and reinforced according to a two-dimensional cross-section frame structure.At this time,the design of the joint position of the frame wall panel becomes the key point.The role of rigid zone of the joint position or the peak-cutting treatment,reasonable consideration of the beneficial effects of axial pressure,can give full play to the performance of reinforced concrete,and achieve good economic results.
