The design of and experimental study on lateral behavior of truss-bolt system
Abstract
Lateral forces acting in truss bolts used in a roadway support was studied. The arching influence on lateral behavior of bolt reinforcing breaking roof has been analyzed. The formula involving lateral force of bolt, tension of rod in truss and the reinforcement behavior have been derived. Simulated experiment test on the stratified roof supported by truss and its parameters optimization have been performed. The test results show that the lateral action of bolts provides an important contribution to roof stability. The theory formula can be used in the design of truss. The reliability of theory has been verified by application examples.
