Hollow Section Roof Truss

Flat trusses with hollow structural sections module for cypecad its integrated 3d structures and cype 3d carries out an automatic analysis and design of coplanar hollow structural section connections like those which are usually provided in flat trusses even though the first version of the module only includes welded connections with circular sections more features will be.

Hollow section roof truss.

It can optimize the truss to either minimize the mass or manufacturing costs. Rectangular hollow section rhs braces and i or h section chord. Warren or pratt truss. Due to symmetry only one segment was analysed by means of fem software fig 1 shows the actual structure and fig.

Arched hollow section trusses in long span structures 121 4 2. Resistance of welds 1. Fem analysis of truss hollow section joint samir lemeš university of zenica. Truss analysed is a roof structure figure 2.

Siko l et al. It is necessary to provide a longitudinal wind girder between braced gable ends in buildings where the roof trusses are not portalized. Generally chord members will be provided from hollow sections. Roof trusses being advantageous there is a need to achieve economy in the design of truss members and also while selecting the sections.

Large scale hollow structural section hss truss tests have been done by dasgupta 1970 edwards and giddings 1974 de koning and wardenier 1979 ogle and kulak 1981 korol 1983 czechowski et al. In this paper an attempt is made to derive economy by designing the truss by using tubular sections and comparing it with conventional steel sections. With it it is possible to optimize the truss with just a few key parameters. Geometry loads and steel grades.

Determining the efficiency of the design process as mentioned in the earlier chapters the efficiency of the single long span truss structure to the multi truss system could be measured by dividing the weight of the. The general arrangement is similar to that described for a transverse wind girder. Introduction the structural elements made of circular or rectangular square hollow sections are usually used for lattice structures roof trusses and lattice. Ssab has developed a unique tool for its customers and designers for designing roof trusses with structural hollow sections.
