组合网架及其应用

组合网架是一种钢和钢筋混凝土组成的空间结构。它把网架上弦杆用钢筋混凝土平板（或带肋板）来代替，下弦杆和腹杆仍然用钢材，形成一种下部是钢结构，上部由钢筋混凝土组合而成的新型空间结构；它充分发挥钢材受拉和混凝土受压的有利条件，使两种不同材料发挥各自强度优势，又使结构的承重和围护功能合二为一，是近年来较具有发展前途的一种结构形式。

Combined Network and Its Application

Combined network is a space structure which is composed of steel and reinforced concrete. It uses the reinforced concrete slab instead of the first quarter pole of the network, the last quarter poles and ventral poles are made by steels, so a new space network is found But its under side is steel structure, above is reinforced concrete, the two materials have their strength, make bearing and bounding combined to work, the structure is new and has widely lookout lately.
