［摘要］通過(guò)工程實(shí)例介紹了輕型木結(jié)構(gòu)建筑抗震設(shè)計(jì)及抗震構(gòu)造措施，分別采用底部剪力法和振型分解反應(yīng)譜法對(duì)結(jié)構(gòu)進(jìn)行水平地震作用計(jì)算。結(jié)果表明，該輕型木結(jié)構(gòu)建筑能滿足抗震設(shè)計(jì)的“三水準(zhǔn)”設(shè)防目標(biāo)。比較了幾種木基剪力墻的有限元模型；并基于SAP2000的分層殼單元，建立了整體結(jié)構(gòu)的有限元模型，計(jì)算了結(jié)構(gòu)的動(dòng)力特性、內(nèi)力及變形并以此作為抗震設(shè)計(jì)的依據(jù)；針對(duì)輕型木結(jié)構(gòu)低延性、高彈性承載力的特點(diǎn)，制定了相應(yīng)的抗震構(gòu)造措施。

Seismic design of a light wood frame building

(Canada Wood China， Shanghai 201206， China)

Abstract:The seismic design and seismic structural measures of light wood frame buildings were introduced through engineering examples. The horizontal seismic response of the structure was calculated by  using the base shear force method and the mode-decomposition response spectrum method respectively. The results show that this light wood frame building can meet the “three-level” fortification target of seismic design. The finite element models of several kinds of wood-based shear walls were compared. Based on the layered shell elements of SAP2000, the finite element model of the overall structure was established, and the dynamic characteristics, internal forces and deformation of the structures were calculated, which was used as the basis for seismic design. For the low ductility and high elastic bearing capacity of the light wood frame building, corresponding seismic structural measures have been formulated.

Keywords:light wood frame construction; seismic design; finite element analysis; seismic structural measures
