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...

The statically-determinate, pin-connected truss is a basic structural element used by engineers to create larger and more complex systems. Truss analysis and design are topics that virtually all students who study engineering mechanics are required to master, many of whom may experience difficulty with initial understanding. The mathematics used to analyze truss systems typically requires lengt...

Structural reliability theory allows structural engineers to take the random nature of structural parameters into account in the analysis and design of structures. The aim of this research is to develop a logical framework for system reliability analysis of truss structures and simultaneous size and geometry optimization of truss structures subjected to structural system reliability constraint....

In this article, a new method of increasing the efficiency combined steel roof trusses is proposed and considered. A rational shape truss, including its topology geometric parameters, was obtained, but without obtaining SSS. provides adjustment SSS in truss by changing upper belt panel length. On basis obtained structural form proposed. It shown that thanks to method, it possible obtain more ef...

a 15-landmark morphometric truss network system was used to investigate the hypothesis of population fragmentation of shad fish alosa braschnicowi borodin, 1904 along the southern caspian sea. a total of 181 a. braschnicowi specimens were caught from six localities, respectively from the west to the east including; astara, rezvanshahr, anzali, tonekabon, sari and miankale. principal component a...

This paper introduces a reliability-based multi-objective design method for spatial truss structures. A multi-objective optimization problem has been defined considering three conflicting objective functions including truss weight, nodal deflection, and failure probability of the entire truss structure with design variables of cross sectional area of the truss members. The failure probability o...

the purpose of this study is to determine the effect of vierendeel panel width and vertical truss spacing ratio in an inelastic behavior of the stf system due to earthquake loads. the stf system is applied to a six-storey building that serves as apartments [2]. the stf system is used in the building in the transverse direction (n-s direction), while in the longitudinal direction (w-e direction)...
