The Development of an optimized long-span cantilever truss system for roofing application

Abstract

The structural efficiency of long-span cantilever trusses significantly relies on the vertical stiffness of the cantilever and its capacity of resistance against the vertical loads. When the cantilever span increases, the deflection of the end tip of the cantilevered truss under vertical loads becomes more pivotal as it reduces the vertical stiffness of the cantilever structure. Therefore, alternative member arrangements and geometry were altered innovatively to develop an optimum configuration of cantilever truss systems with a high capacity-to-weight ratio. This thesis illustrates the development approaches, numerical and analytical calculations of the decision-making process, and a detailed discussion of selected configurations and their performance
