［摘要］在預(yù)制混凝土夾心保溫外掛墻板與主體結(jié)構(gòu)間設(shè)置U型鋼板消能器形成的減震外掛墻板，在地震作用下可利用外掛墻板與主體結(jié)構(gòu)間的相對滑移變形耗散地震能量，從而達到減小主體結(jié)構(gòu)損傷的目的。在對含減震外掛墻板裝配式混凝土聯(lián)肢剪力墻進行擬靜力試驗研究的基礎(chǔ)上，對其數(shù)值模擬分析方法進行了研究。提出了兩種分別適用于構(gòu)件層次和結(jié)構(gòu)層次的精細和簡化有限元模型的建模方法。采用兩種模型對試驗試件的受力性能進行了數(shù)值模擬分析，并與試驗結(jié)果進行了對比。結(jié)果表明，兩種模型均有較高的計算精度，能夠較好地反映結(jié)構(gòu)的受力情況。

Abstract:The energy dissipating cladding panel formed by a U-shaped steel damper is set between the precast concrete sandwich cladding panel and the main structure. Under the action of an earthquake, the relative sliding deformation between the cladding panel and the main structure can be used to dissipate seismic energy to achieve the purpose of reducing the damage of the main structure. On the basis of the pseudo-static test research on the prefabricated concrete joint shear wall with energy dissipating cladding panel, the numerical simulation analysis method was studied. Two modeling methods of fine and simplified finite element models, which are suitable for component level and structure level, were proposed. Two models were used to carry out numerical simulation analysis on the mechanical properties of the test specimens, and the results were compared with the test results. The results show that the two models have higher calculation accuracy and can better reflect the force of the structure.
