结果表明随着耦连比的增大试件的抗侧承载力提高但破坏位移减小；试件由钢连梁首先优化一下这段话使之具有学术规范性同时语句通顺符合逻辑：屈服逐渐过渡到钢连梁与组合墙肢同步屈服；此外墙肢间内力重分布的现象逐渐明显各层钢连梁也趋向同步屈服。

The results indicate that as the coupling ratio increases, the lateral bearing capacity of the specimen improves, but the failure displacement decreases. The optimization of the specimen by steel beams precedes the yielding transition to synchronous yielding of the steel beams and composite wall limbs. Furthermore, the phenomenon of redistribution of internal forces between wall limbs becomes increasingly evident, and the steel beams on each floor tend to yield synchronously. These findings adhere to academic standards and present a coherent and logical statement.
