COMPUTER PROGRAM FOR THE ANALYSIS OF CURVED STEEL GIRDER BRIDGES. INTERIM REPORT
The Kurv87 computer program was developed to provide an easy-to-use analysis tool for curved as well as straight steel girder bridges. The philosophy behind this objective was to set certain limitations to balance the goals of an easy-to-use program and one which is applicable to many bridge geometries. The program easily handles the following types of bridge problems: (1) erection procedure in which multiple stages and differing boundary conditions can be superimposed on each other; (2) S-curved bridges with intermittent straight segments; (3) support settlements and specified support stiffnesses; (4) multiple truck or lane loadings; (5) slight exterior support skew and severe or slight interior support skew; (6) dead loads superimposed on live loads; (7) orthotropic slab properties over negative moment regions; and (8) three diaphragm configurations with or without bottom lateral bracing. The program also provides the capacity to add segments of the bridge, which do not correspond to the data generator requirements, between data generated ones so that most any bridge can be analyzed on varying degrees of input difficulty. A parameter study was done to study the accuracy of the V-load method and to study curved girder behavior.
