Hollow Section Roof Truss

It can optimize the truss to either minimize the mass or manufacturing costs.

Hollow section roof truss.

Ssab has developed a unique tool for its customers and designers for designing roof trusses with structural hollow sections. 1984 philiastides 1988 and frater and packer 1992 with additional analysis performed by coutie and saidani 1989 1991 on tests by philiastides 1988. With it it is possible to optimize the truss with just a few key parameters. 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.

Geometry loads and steel grades. Truss analysed is a roof structure figure 2. 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. Roof trusses being advantageous there is a need to achieve economy in the design of truss members and also while selecting the sections.

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. 2 shows truss section analysed with fem software the.
