Research of arrangements of web members and feasible styles for truss members of the staggered truss system

The pratt truss with diagonals omitted for passageways is the most efficient type of truss to be used in the staggered truss(system).To be economical for mass production,the trusses throughout the building should be identical in form and type of members,designed so that jigs can accommodate the slight differences in member dimensions.This paper analyzes the varieties of the load bearing behavior of the truss from the different location of the vierendeel panel and the different arrangements of web members,and it illustrates that the vierendeel panel can't be placed at the end of the truss.It also give the feasible styles for web members of the staggered truss system.
