［摘要］采用SAP2000和YJK對某22m直徑的熟料庫筒倉結(jié)構(gòu)進行了分析和設(shè)計，校核了兩款軟件的分析結(jié)果，保證了計算模型的精度。并結(jié)合筒倉結(jié)構(gòu)設(shè)計規(guī)范對比了貯料荷載、內(nèi)外溫差及季節(jié)溫差對倉壁內(nèi)力的影響，分析結(jié)果表明，內(nèi)外溫差會對倉壁產(chǎn)生較大的環(huán)向力和豎向彎矩，設(shè)計時應(yīng)充分考慮。對比分析表明，在同樣的內(nèi)外溫差作用下，倉壁越薄，倉壁所受環(huán)向力及豎向彎矩越小，故在內(nèi)外溫差較大的筒倉結(jié)構(gòu)設(shè)計中應(yīng)適當(dāng)控制壁厚。

Abstract： A 22m diameter clinker silo was analyzed and designed with the SAP2000 and YJK, the two calculation results were checked to ensure the accuracy of the model. The internal force of the silo wall was studied under the action of the stored material load and temperature load in combination with the code of reinforced concrete silos. The results show that the differential temperature change would have bigger effects to the hoop force and vertical bending moment, it should be paid more attention in the design. Analysis also shows that internal forces caused by temperature change are directly related with the thickness of silo wall, the wall thickness should be controlled if the differential temperature change is large.
Keywords： clinker silo; temperature difference between inside and outside; diagonally stored
