Truss models for the design of reinforced concrete beams subject to biaxial shear

摘要

Spatial truss models are developed for the design of reinforced concrete beamsrnsubject to biaxial shear forces. They are derived from a resolution of the vector of thernresultant shear force and applied to beams with rectangular cross sections. Thernmodels consist of tensile struts of stirrups and longitudinal bars, spatially inclinedrnshear struts as well as compressive struts stiffening the stirrup corners. They arernfurther elaborated to derive charts for the stirrup design. An example shows thernpractical application.
