平板网架是由许多杆件,沿平面或曲面按照一定规律组成的高次超静定的空间结构,是当前国内外正在研究推广的一种较好的新结构型式。它改变了一般桁架的平面受力状态,能够承受来自各个方向的荷载;杆件互相起支撑作用,故稳定性好、空间刚度大、安全度高,对于抗震非常有利;同时由于空间受力,平板网架较平面结构自重轻,节约钢材、水泥和木材;加之杆件韵律性强,使建筑布置灵活、美观、轻巧大方,便于建筑处理;建筑高度小,能更有效地利用建筑空间,获得良好的经济效果。
The flat grid is a high-order statically indeterminate space structure composed of a number of rods, along a plane or curved surface according to a certain rule, and is a better new structure type currently being researched and promoted at home and abroad. It changes the general stress state of the general truss and can bear loads from all directions; the rods support each other, so they have good stability, large space stiffness, and high safety, and are very beneficial to earthquake resistance; at the same time, due to space forces, The flat plate frame has a lighter weight than the plane structure and saves steel, cement and wood. In addition, the rhythm of the bars makes the building layout flexible, beautiful, lightweight and easy to handle, and the construction is easy to handle. The building height is small, and the building space can be used more efficiently to obtain Good economic effect.
