In this paper,the finite element method for elastic stable theory is ueed to deal with the practical laed-bearing properties of door-type steel pipe scaffold linking in different way and analyze main factors influencing the load bearing ability of scaffold.

The application of scaffold slippage in large-span shell installation and its development;

The roof of this building is plate steel network frame structure,and the construction scheme of slip scaffold for installation in bulk is selected.

As the horizontal rods are made of timber,the portal-frame scaffolding shows several disadvantages in practice when used in form panel bracing,which have limited its wide applications.

Analysis and control of construction security risk of high frameworksupport system for fastener-style steel pipe scaffolding;
