Beam-Tie형 지붕트러스의 허용하중 산정방법에 관한 연구 ( A Study on the Calculating Method of Allowable Load for Beam-tie Type Roof Truss )

In general, a is one of the most efficient types of roof trusses. It saves the amount of steel, construction time, and labor required for constructing a roof truss, because it is a simple frame truss made of a rolled steel produced in a plant and prefabricated on construction site. In spite of such advantages, a beam-tie truss has not been widely used due to the problems of analyzing a statically indeterminate structure and estimating section sizes, and due to a complex design process. This research develops the equations and process for calculating allowable load of main frame and required area of tie-rod. Using this, the effective section sizes can be easily estimated.
