Shear action is an important factor in the failure of reinforced                concrete structures.  A softened truss model theory has been                    developed that is capable of predicting the behavior of various                 types of structures when shear is predominant.  The first                       objective is to generalize the softened truss model theory so                   that it can be applied to situations where shear (torsion) is                   combined with axial loads.  The second objective is to perform                  tests on 40 full.size reinforced concrete panels in order to                    determine the material laws required in the general theory,                     including the softening law, the constitutive law of cracks, and                the law governing the contribution of concrete.  The research                   will be carried out in a $440,000 panel.testing facility recently               completed at the University of Houston.  This facility consists                 of a giant steel frame embedded with 40 jacks of 100.ton capacity               each, which can test reinforced concrete panels 55 inches square                and up to 16 inches thick.  Establishment of a general truss                    model theory in conjunction with the finite element method will                 permit one to predict the behavior of a whole range of structures               subjected to membrane stresses (walls and shells).
