［摘要］以點支承外掛墻板為研究對象，討論了計算節(jié)點時的地震作用標(biāo)準(zhǔn)值，建議節(jié)點在罕遇地震下不屈服并給出了相應(yīng)的動力放大系數(shù)建議值；分析了不同連接形式、不同荷載工況下的節(jié)點受力并推導(dǎo)得出相應(yīng)公式；找出了節(jié)點變形設(shè)計的原因和節(jié)點變形的計算思路，并研究了主體構(gòu)件設(shè)計對節(jié)點變形設(shè)計的影響，建議從提升節(jié)點適應(yīng)變形的能力和適當(dāng)限制主體支承構(gòu)件的變形兩個方面解決外掛墻板節(jié)點與主體結(jié)構(gòu)的相對變形問題。

Abstract:The research focus on the point-supporting external wallboard. First of all, the standard load under seismic of point-supporting external wallboards′ nodes was discussed. Moreover, in order to avoid the yield when the rare earthquake occur, the dynamic amplification factors were suggested to carried out, and the recommended values of that were also put forward. After that, the formulas which can be used to calculate the nodes′ force of different connection form under different load types were derived. Finally, the deformation of point-supporting external wallboards′ nodes was discussed, including the reason of concerning the deformation in design and the calculation of it. Besides, the relationship between the deformation of structure and point-supporting external wallboards′ nodes was put forward. It is suggested that the relative deformation of the external wall panel and the structure to be solved from increasing the facade panel’s deformation capacity and restricting the deformation of the structure.
