| Abstract: | The paper analyzes the nonlinear numerical value of 7 piers-samples round and ribbed to strengthen in their interios by finite element program of MARC,has obtained a curve of load-displacement relation under action of given vertical and horizantal reciprocating loads,and investigates effects of steel pipe's radius-thickness ratio and pier column's length-thickness ratio on the sesmic performances like the limit bearing capacity of round pier ribbed in its interior,its ductility along with energy absorption. |
