| 摘要： | This article presents a refinement of the rotating-angle softened truss model (RA-STM) for prestressed concrete (PC) membrane elements. To refine the RA-STM, an efficient solution procedure to solve the set of nonlinear equations is presented. Appropriate average stress-strain relationships for concrete and steel bars are also used in the solution procedure. The theoretical results obtained from the refined RA-STM are compared with some experimental results found in the literature and also with the original RA-STM. It is shown that the refined RA-STM captures better the behavior of PC membrane elements under shear and also predicts better the shear strength. |
