| Abstract: | A simplified softened truss model originated from the truss concept and satisfied equilibrium,compatibility,and the constitutive laws of cracked reinforced concrete,is expounded with its transitive path and design procedure.A simplified softened truss model for design and analyses of the shear strength of RC short corbels is proposed,the parameters reviewed include the concrete strength,the shear span-depth ratio,and the amount of horizontal hoop.It is therefore recommended that the current shear design procedures for RC short corbels be reformed and utilized to incorporate with the actual shear-resisting mechanisms as postulated by the simplified softened truss model.The calculated values are in good agreement with the check values. |
