［摘要］山東航海實訓(xùn)中心項目長約150m，船身外圍護(hù)結(jié)構(gòu)采用整體鋼板造型。由于外墻鋼板為板殼結(jié)構(gòu),長度較大，且受太陽輻射等的影響，溫度作用對其結(jié)構(gòu)的影響很大。對外墻鋼板在太陽輻射、水體熱傳導(dǎo)等作用下的非均勻溫度場進(jìn)行了數(shù)值模擬；在考慮材料和幾何非線性的情況下，研究了非均勻溫度場對外墻鋼板以及整體結(jié)構(gòu)的變形和應(yīng)力影響。綜合分析結(jié)果、當(dāng)?shù)貧庀笥涗浖笆┕みM(jìn)程，提出了外墻鋼板及主體結(jié)構(gòu)合攏的溫度分別為23～27℃和7～17℃。對比了在均勻溫度場和非均勻溫度場作用下，外墻鋼板及整體結(jié)構(gòu)的溫度作用效應(yīng)。結(jié)果表明，在兩種溫度場作用下，結(jié)構(gòu)整體均仍處于彈性狀態(tài)，外墻鋼板變形可滿足建筑外觀需求。

Abstract:Shandong Training Center of Navigation is 150m long, and the exterior-protected structure of the hull structure is made of integral steel plate structure. Because the outer wall steel plate is the shell and plate structure with large length and it is affected by the solar radiation, the temperature action has the very large influence to its structure. Numerical simulation was conducted on the non-uniform temperature field consisting of outer wall steel plate under the solar radiation and water heat conduction. In consideration of material and geometrical nonlinearities, the effect of non-uniform temperature field on the deformation and stress of the outer wall steel plate and the overall structure was studied. Based on comprehensive analysis of simulation analysis results, local weather records and construction process, it put forward the closure temperature of 23～27℃ and 7～17℃ respectively for the outer wall steel plate and the main structure. The temperature effect of the outer wall steel plate and the whole structure under the uniform temperature field and non-uniform temperature field were compared. The results show that under the influence of two temperature fields, the whole structure is still in an elastic state, and the deformation of the outer wall steel plate can meet the architectural appearance requirement.
Keywords:solar radiation; non uniform temperature field; temperature effect
