Some Characteristics of Grid Structure
-Light deadweight, high stiffness, super aseismic performance
-Industrial production, convenient installation, vast flexibility
-Free span
Grid type selection is considered the building flat shape, construction requirements, load, bearing condition and economic factors.
-Small span: <30m
-Middle span: 30m-60m
-Large span: >60m
I. Plane Girder System
Rectangle plane, perimeter support, side-to-length ratio<1.5, either span is acceptable.
Rectangle plane, perimeter support, side-to-length ratio<1.5, either span is acceptable.
Rectangle plane, perimeter support, side-to-length ratio>2.
Round plane or polygon plane, regular net surrounded, especially for large span construction.
II. Quadrangular Pyramid System
III. Standard Pyrometric Cone System
