Reinforced and prestressed concrete structures subjected to shear and torsion are currently being designed by empirical or semi-empirical methods. No satisfactory theory has yet been developed to predict the shear strength and behavior of structures, such as shear walls and nuclear containment vessels under earthquake or wind motion. The main purpose of this research is to develop a general truss model theory which can take into account the contribution of concrete, the constitutive law of cracks, and the softening effect of concrete in structures. To establish the parameters required in the general truss model theory, a minimum of 50 shear panels will have to be tested. Each of the panels will be 250 x 250 x 12.7 cm. (98 x 98 x 5 in.) Since no suitable facilities are available in the United States, the tests will be carried out at the Kajima Institute of Construction Technology in Japan on the basis of research cooperation.

钢筋混凝土结构和预应力混凝土结构承受剪力和 扭转目前正在设计的经验或半经验 方法. 还没有令人满意的理论来预测 结构的剪切强度和性能，如剪力墙和 核安全壳在地震或风的运动。 主要 本研究的目的是发展一种通用的桁架模型理论 它可以考虑混凝土的贡献， 裂缝的本构关系和混凝土的软化效应 结构. 建立一般桁架所需的参数 根据模型理论，至少需要测试50个剪切板。 每个面板将为250 x 250 x 12.7 cm。(98 x 98 x 5英寸） 由于美国没有合适的设施， 试验将在鹿岛建设研究所进行 在日本技术的基础上进行研究合作。
