In this article, the rational constructive form of combined steel truss with a span 30 meters is received, 59% fewer elements than typical. Calculated regulation methods are offered stress-deformation state (SDS) trusses, which make it possible to increase their efficiency. Methods estimated SDS in trusses given: change stiffness rodsand creation eccentricities nodes connecting lattice upper be...

The objective of this research was to use a three-dimensional (3D) analysis method to evaluate "system effects" in light-frame roof truss assemblies. The goal of this study was to develop an improved and practical design method for 3D roof truss assemblies used in residential construction. A truss plate manufacturer (TPM) design software was used to layout assemblies and to design individual tr...

An integrated truss design methodology based on homogenization-based topology optimization is proposed. After performing continuum topology optimization to obtain the optimal structural configuration, in the case that the percentage usage of the materials is low, the methodology can automatically proceed to the truss optimization based on the model, and achieve the optimum truss structure meeti...
