Paper Title:
Parameter Analysis of Compressive Web Members in Plane Tubular Truss with Simple Joints
  Abstract

Stability design for compressive web members of tubular structure could be simplified as determination of effective length of compressive web members. There were no design provisions for effective length of compressive web members in tubular truss in the current design code of steel structure (GB50017-2003). Based on previous research achievements, parameter analyses on compressive web members in tubular truss with simple joints were performed using finite element software, in which diameter ratios and wall thickness ratios of web members to chord members as well as different construction styles were considered. After analyzing 3 series, sum to 42 FEM model, the results indicates that stiffness ratio of web members to chord members has a significant effect on effective length of compressive web members, thus increasing width ratio of chord members to web members could decrease effective length of compressive web members; the effective length of compressive web member in circular tube truss is suitable to be 0.75 in-plane and out-plane, and 0.8 for the mixed truss of circular and square tube.
