Grid Structure Design

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
