Abstract
ABSTRACT FORTRAN programs are presented for the design of a Howe steel roof system in accordance with BS5950 (1985) at a constant reliability level. The concept of the design was built upon the First-Order Reliability Method (FORM) and System Reliability (SYSREL). The reliability indices of components making the truss system were observed to vary as the dead/live load ratio increases. The overall safety index of the system is lower than the safety indices of the individual components and joints. The reliability program developed iteratively selects optimum sectional properties which offer a target reliability level when inherent uncertainties in the design variables are systematically considered.
