［摘要］介紹了輕型木框架剪力墻結(jié)構(gòu)中面板與木框架釘節(jié)點(diǎn)的試驗研究，按照ASTM-F1575-03標(biāo)準(zhǔn)對兩種不同型號的中國釘子各做了10個試件的抗彎試驗；并按照ASTM-F1676-03標(biāo)準(zhǔn)進(jìn)行了兩組各10個試件的單向拉伸荷載試驗，一組荷載垂直于木材紋路方向，另一組荷載平行于木材紋路方向。通過試驗發(fā)現(xiàn),不同的釘子規(guī)格對釘節(jié)點(diǎn)性能的影響不是很大。在國外常用的指數(shù)型釘節(jié)點(diǎn)模型的基礎(chǔ)上，建立了一種適用于中國釘子兩個方向釘節(jié)點(diǎn)的修正模型，該模型為利用有限元軟件分析輕型木框架剪力墻結(jié)構(gòu)提供了面板與木框架釘節(jié)點(diǎn)連接性能的基礎(chǔ)資料。

Abstract:Test research on nail joints between sheathing-to-wood connections on light wood frame shear walls was introduced. Two different types of Chinese screw nails were used to conduct bending test according to ASTM-F1575-03- There were 10 nails of each nail type. Based on ASTM-F1676-03, one directional tensile tests of two groups, one with perpendicular-to-grain and the other with parallel-to-grain nail joints specimens using two standards nails mentioned above, were carried out. Each group has 10 specimens. It was found that different standards of nails had little effect on the performance of nail joints. A modified model which was suitable to domestic nails in two directions was established on the basis of exponential model. Useful data on the performance of sheathing-to-wood connections, which can be integrated into the finite element software to analyze wood frame construction, were provided.

Keywords:wood frame shear wall; nail joints; test research; model
