Calculating Methods of the Stability Bearing Capacity of the Long-span Z-purlin Subjected to Wind Suction;

The FEA on diaphragm-braced C-shape purlin;

The application of continuous purlin of cold-formed thin-walled steel in light-weight steel structure;

Experimental study on stability bearing capacity of purlin under wind suction in the hangar of TAECO;

Based on the experience of design,a number of problems that need to be dealed with carefully are pointed out which contins:apply-extension, the bracing system,place purline .

In this paper,detailed steps and key points in designning of light-gauge steel framing will be introduced, including column spacing selection of portal frame, structure system layout, selection of load value, material selection, design of portal frame structure and its members, and design of brace, column brace and purline.

This article mainly is through checking computations the load on the metope purline of the Big Span in the Jiugang thermoelectricity technical alteration engineering workshop,proves the metope purline s span of the light steel structur can advance 8m on the conventional 6m in Jiayuguan.

Atlas of steel purlin and girt is established by China Institute of Building Standard Design & Research.
