［摘要］結合鋼網(wǎng)架與混凝土框架結構的實際工程項目，考慮采空沉降區(qū)變形對結構內(nèi)力的影響，采用MIDAS/Gen軟件，建立鋼網(wǎng)架與下部鋼筋混凝土框架結構的整體模型，輸入采空區(qū)地表變形，提取網(wǎng)架各桿件的內(nèi)力，分析采空區(qū)變形對網(wǎng)架內(nèi)力的影響大小。給出采空沉降區(qū)使用鋼網(wǎng)架與混凝土框架結構體系的可行性結論，對相關結構設計提出設計建議。
［關鍵詞］鋼網(wǎng)架與混凝土框架結構； 采空區(qū)； 地表變形； MIDAS/Gen

Abstract： Combined with practical project of steel grid and reinforced concrete frame structure, considering the influence of deformation of mining subsidence area on structural internal force, using MIDAS/Gen software, the whole model of the steel grid and the reinforced concrete frame structure was built, surface deformation of mining subsidence area was input, the internal force of each rod of steel grid was extracted, the influence of mining subsidence area′s deformation on steel grid′s internal force was analyzed. Conclusions of the feasibility of using structural system of steel grid and concrete frame are made, and related suggestions for the design of structure were put forward.
Keywords： streel truss and RC frame structure; mining subsidence area; surface deformation; MIDAS/Gen
