充分利用现有的实验设备，分别对实验室现有的反力墙和自平衡加载装置进行改进设计，使其满足空间复杂节点加载试验的需求。通过对两种改进装置加载试验效果的对比分析，评价两者的优缺点。反力墙加载装置对平面杆件体系组成节点弹性阶段受力状态的验证效果较好，自平衡加载装置可以较为准确地反映节点的实际受力状况，可用于复杂钢节点，特别是多支管钢节点极限承载力的试验研究。结果表明，该改进设计能满足空间复杂节点试验的需求，拓展了结构实验教学研究范围。
充分利用現有的實驗設備，分彆對實驗室現有的反力牆和自平衡加載裝置進行改進設計，使其滿足空間複雜節點加載試驗的需求。通過對兩種改進裝置加載試驗效果的對比分析，評價兩者的優缺點。反力牆加載裝置對平麵桿件體繫組成節點彈性階段受力狀態的驗證效果較好，自平衡加載裝置可以較為準確地反映節點的實際受力狀況，可用于複雜鋼節點，特彆是多支管鋼節點極限承載力的試驗研究。結果錶明，該改進設計能滿足空間複雜節點試驗的需求，拓展瞭結構實驗教學研究範圍。
