Abstract:	吊拉組合橋造型優美，由主梁、橋塔、主纜、斜拉索及垂直吊索所組合而成，兼具了懸索橋和斜張橋的許多優點，為一種新型結構體系的橋梁。相較於懸索橋，它具有較高的抗風穩定性；相較於斜張橋，它具有較低的橋塔高度，因此自錨式吊拉組合橋在國內具有相當大的應用空間。為了進一步瞭解自錨式吊拉組合橋在國內的適用性，本為擬探討自錨式吊拉組合橋的地震反應特性。　　本文利用ANSYS套裝軟體，以反應譜法進行自錨式吊拉組合橋於順橋向地震作用時之地震反應分析，藉以瞭解自錨式吊拉組合橋之地震反應特性；另外，亦進行具有不同幾何形狀與不同子 A combined cable-stayed suspension bridge, including main girder, tower, main cable, vertical hangers and stayed cables, is characterized by its elegant structural shape. It possesses combines merits of both a self-anchored suspension bridge and a cable-s
