Study on the Stability of the Bearing Capacity of Wedge Connected Scaffold

摘要

Experimental data obtained from full-scale experiments determines the stiffness of wedge connected of scaffold. A finite element model is developed using semi-rigid scaffold node mode. And a reasonable combination of longitudinal span, transverse span and step distance is obtained. The results accord with the relevant standard of vertical load. It provides a theoretical support for the application of wedge connected scaffold. Additionally, the study explores the safety height of the wedge connected scaffold with or without bridging. It provides a theoretical basis for technical regulations.
