新型竹质工程材料抗震房屋基本构件力学性能试验研究

Experimental Study on Mechanical Properties of Basic Components for a New Anti-Seismic Room with Bamboo Engineering Materials

基于竹材的优良特性和竹结构优异的抗震性能,课题组提出采用竹质工程材料建造新型抗震安居房,为汶川地震后的村镇住宅重建提供一个良好的选择方案。针对新型竹质工程材料抗震房屋结构设计计算的需要,对其所涉及的竹质工程材料的基本构件进行了足尺的试验研究,包括竹材重组材柱、竹材层积材梁。通过试验,分析了梁和柱的破坏形式,确定了强度和弹性模量的设计取值。

Based on the good characteristics of bamboo and the excellent structures, bamboo seismic performance of bamboo engineering materials were presented to construct a new anti - seismic living room and which provided a good alternative scheme for the reconstruction of residential villages and towns after Wenchuan earthquake. For the design and analysis of the anti - seismic structure with a new type of bamboo engineering materials, its basic components were full - scale tested, including the reconstituted bamboo columns, laminated bamboo beams. The failure modes of beams and columns were analyzed and the strength and elastic modulus values were defined for the design.
