逆L形正八角形断面鋼製橋脚の耐震性能実験

Abstract

Inverted L-shaped pier is often used in urban area, where there are many cross roads and curved roads. The research work has not been performed sufficiently so far for the seismic performance of such not simple shape pier. This study demonstrates the experimental research for the seismic performance of the inverted L-shaped steel piers with octagonal section. The L-shaped pier sustains eccentric forces in both directions vertical and horizontal .So，main parameter chosen in the test is the eccentricity related to e/r，where r is the radius of gyration. The important results are obtained from the test such as the maximum horizontal strength，ductility and energy absorption capacity referred to the eccentricity parameter.
