Descus I
for plate girders

Abstract: The computer program DESCUS I will perform the complete analysis and partial design of a horizontally curved bridge composed of flanged steel sections which act either compositely or noncompositely with a concrete deck. The program can be run using either Working Stress Design (WSD) method, Load Factor Design (LFD) method or the LRFD specifications for curved girders. DESCUS I incorporates the LRFD loadings. The bridge may be of arbitrary plan configuration and can be continuous and skewed over supports. The girders may have high degree of curvature, may be nonconcentric, bifurcated, and may contain hinges.

Descus II
for box girders

Abstract: The computer program DESCUS II will perform the complete analysis of a horizontally curved bridge composed of steel box sections which act either compositely or noncompositely with a concrete deck. The program can use either the Working Stress Design (WSD) method, the Load Factor Design method or the Load Resistance Factor Design (LRFD) method. DESCUS II has incorporated the LRFD loadings. The bridge may be of arbitrary plan configuration and can be continuous and skewed over supports. The box girders may have a high degree of curvature and may be non-concentric.
