ULTIMATE STRENGTH AND DUCTILITY ANALYSIS OF THE STIFFENED CONCRETE PIERS

A new finite element procedure is developed to study the ultimate strength and ductility behavior of the concrete piers up to softening stage. In the computer code, a degenerate isoparametric curved shell element with layered model is adopted. The arc-length algorithm combined with line search acceleration is employed to overcome the numerical difficulties near and beyond the failure stage. The structural responses of the concrete piers are simulated and compared with experimental results, which shows the efficiency and reliability of the computer code. The stiffening efficiency with different stiffening lengths is discussed, and other two practical stepped concrete piers are also studied. For the covering abstract see ITRD E111699.
