引用本文摘 ? 要：通過對4片新型EPS模塊澆筑墻體進行軸心和偏心受壓試驗，研究了試件的破壞形態、極限承載力和變形規律。在試驗基礎上，利用ABAQUS軟件建立了新型EPS模塊澆筑墻體有限元模型，并對試件的極限承載力進行了對比分析。結果表明：新型EPS模塊內存在連接橋，墻體的破壞首先出現在連接橋處，最終破壞形式為受壓區混凝土破壞；隨著偏心距逐漸增大，墻體的極限承載力明顯降低，應變與普通混凝土墻體的變化相似；有限元分析結果與試驗結果吻合良好，可為工程設計提供分析方法和理論依據。 Abstract: Four new EPS module cast-in-place walls were tested under axial compression and eccentric compression, ?and the failure mode, ultimate bearing capacity and deformation law of the specimens were studied. On the basis of the test, the finite element model of new EPS cast-in-place wall was established by using ABAQUS software, and the ultimate bearing capacity of the specimen was compared and analyzed. The results show that there is a connecting bridge in the new EPS module, and the wall failure first appears at the connecting bridge, and the final failure mode is concrete failure in the compression zone. With the increase of the eccentricity, the ultimate bearing capacity of the wall decreases obviously, and the change of the concrete strain is similar to that of the ordinary concrete wall. The results of finite element analysis are in good agreement with the test results, which can provide analysis method and theoretical basis for engineering design.
