错列桁架大开间结构体系的基本结构组成是柱子、平面桁架和楼板。柱子沿房屋外侧周边布置,中间无柱,桁架在相邻柱列上下层交错布置,楼板端搁置在桁架的上弦,另一端则支承在相邻桁架的下弦。现主要对钢管混凝土柱、桁架及大开间楼板进行设计。 The basic structure of the staggered trusses wide-open structural system consists of columns, planar trusses and floors. The pillars are arranged along the periphery of the house, with no pillars in the middle. The truss is staggered on the upper and lower pillars of the adjacent pillars. The floor end rests on the upper chord of the truss and the other end supports the lower chord of the adjacent truss. Now the main concrete-filled steel tube columns, trusses and large open floor design.
