2、ervisor： Zhang jian ABSTRACT In domestic construction market, steel tubular scaffold with couplers have been widely used. But the frequent collapse accidents are also a boring problem. Because of

3、 the laggard marketing and management system, and lack of the understanding in the building company, the formwork – support systerm are not calculated carefully, and the strength and stability of the formw

4、ork- support system are not enough. The paper reviewed the development of scaffold technology in our country . Contrasted and analyzed several theories about the calculation of scaffold and analy

5、zed accidents of scaffolds that occurred frequently. It is useful for following study. Firstly, the paper contrasted and analyzed several model about the calculation of scaffold, thus raised trus
