摘要:
 钢-混凝土组合梁充分利用钢材和混凝土这两种材料特性，结构刚度大，经济效益好。但在结构的负弯矩区混凝土桥面板受拉、钢梁受压对结构受力不利。针对这一问题，对某半漂浮体系斜拉桥零号块负弯矩区桥面板进行了有限元数值仿真分析，研究桥面板在成桥状态的局部受力性能，针对其受力特点，提出了三种改进措施以改善其受力性能并比较了各种措施的效果。
Abstract:
 Material properties of steel and concrete have been made full use in steel concrete composite beam, so it has high structural stiffness and good economic benefit. However, the concrete bridge deck bears tension in negative moment area, and the steel beam bears stress, which is disadvantageous to structural mechanical behavior. Aiming at this question, a finite element model of the Zero block in negative moment area of semi floating cable stayed bridge is built, and the local mechanical performance of bridge deck under completed status is studied. Based on the research result, three improvement measures have been proposed and improvement effects of methods have been researched.
