Advantages of net frame structure in the application of large-span roof engineering

The net frame structure belongs to the articulated rod system in the too-span space structure system, with good structural overall performance, large spatial rigidity, force table, uniformity, material province, single rod, and each rod material can give full play to the role of making and installing convenient. Net frame structure rod arrangement is flexible, suitable for various shapes of buildings and large spans, large column spacing of the roof knot. Net frame has the advantages of good overall rigidity, good overall performance, can withstand accidents, ideal seismic performance, saving steel. 

It is characterised by:

(1) It can give full play to the material strength advantage of concrete under pressure and steel under tension;

(2) It makes the load-bearing and enclosing functions of the structure into one;

(3) It is a space structure with a combination of plate system, beam system and rod system working in concert, with large vertical and horizontal stiffness and good seismic performance;

(4) It is used for single-span structure, which can avoid negative bending moment.
