摘要:为了推广胶合竹材在轻型木结构等建筑结构中的运用，试验研究了8片采用10mm厚国产竹胶合板作为覆面板的轻型木结构框架剪力墙的加工方法和抗震性能。分别采用51mm长的圆射钉和51mm长的钢排钉制作了两种竹胶板轻型木框架剪力墙。根据美国ASTM-E2126-09墙体试验标准，进行了该类型墙体的单调加载及滞回加载试验。试验结果表明，在采用两种相同长度但不同延性的国产射钉的情况下，该类型剪力墙单位长度承载力为5.2 kN/m和6.2 kN/m，在水平位移100mm以前能够保持85%以上的承载能力。墙体具有良好的承载力及延性，其力学性能可以满足目前国内外规范针对轻型木结构墙体提出的抗侧向力设计要求。本研究成果有利于扩展绿色环保的竹材在主要结构构件中的应用，进一步推动我国竹木结构的发展。

Abstract: In order to promote the application of bamboo materials in construction industry, this paper reports lateral loading test results of lightweight woodframe shear walls with ply-bamboo sheathing panels. ASTM-E2126-09 is selected as the experimental guideline for the monotonic and cyclic tests of 8 shear walls. Two types of shear walls were made using two different nails, 51mm long nail-gun driven nails and 51mm long nail staples. The bearing capacity was 5.2 kN/m and 6.2 kN/m respectively. Shear walls kept its integrity and majority of its bearing capacity when the lateral displacement was below 100mm. Test results showed that the application of ply-bamboo sheathing panel can satisfy the bearing capacity requirements of shear walls designed as structural elements, according to current codes for timber structures.

Keywords: lightweight woodframe; ply-bamboo sheathing panel; shear wall; nails; static test; quasi-static test; seismic performance.
