Structural and Economic Viability of 2D/3D Finite Element Analysis of Conical Arched Roof Truss

Abstract

ABSTRACT ABSTRACTArch and conical roof trusses are employed when dealing with large span roof trusses. But a Arch and conical roof trusses are employed when dealing with large span roof trusses. But a Arch and conical roof trusses are employed when dealing with large span roof trusses. But a Arch and conical roof trusses are employed when dealing with large span roof trusses. But a geometrical shapes may lead to a better economical sections and a means of dealing with larger spans of roof truss geometrical shapes may lead to a better economical sections and a means of dealing with larger spans of roof truss geometrical shapes may lead to a better economical sections and a means of dealing with larger spans of roof truss geometrical shapes may lead to a better economical sections and a means of dealing with larger spans of roof truss that are not suitable for an arch or conical roof truss. Consequently, this paper examines the structural and that are not suitable for an arch or conical roof truss. Consequently, this paper examines the structural and that are not suitable for an arch or conical roof truss. Consequently, this paper examines the structural and that are not suitable for an arch or conical roof truss. Consequently, this paper examines the structural and economic economic economic economic viability of viability of viability of viability of arched arched arched arched conical roof truss conical roof truss conical roof truss conical roof truss the results showed that truss members were subjected to higher axial forces in 2D analysis than 3D analysis, which the results showed that truss members were subjected to higher axial forces in 2D analysis than 3D analysis, which the results showed that truss members were subjected to higher axial forces in 2D analysis than 3D analysis, which the results showed that truss members were subjected to higher axial forces in 2D analysis than 3D analysis, which will result to overdesign of the st will result to overdesign of the st will result to overdesign of the st will result to overdesign of the structural members and the attendant high construction cost. There are some ructural members and the attendant high construction cost. There are some ructural members and the attendant high construction cost. There are some ructural members and the attendant high construction cost. There are some variations observed in the axial forces for trusses located at edges of variations observed in the axial forces for trusses located at edges of variations observed in the axial forces for trusses located at edges of variations observed in the axial forces for trusses located at edges of located mid located mid located mid located mid----point between two point between two point between two point between two polygonal polygonal polygonal polygonal properties of the members as well as in the fabrication and installation cost. properties of the members as well as in the fabrication and installation cost. properties of the members as well as in the fabrication and inst...
