［摘要］以單層坡屋頂原型房屋的1/2縮尺振動(dòng)臺(tái)模型為對(duì)象，對(duì)現(xiàn)代夯土建筑在夯土材料、夯筑機(jī)具、夯筑工藝、抗震構(gòu)造措施等方面的改良技術(shù)做了簡(jiǎn)要說明，重點(diǎn)對(duì)結(jié)構(gòu)模型在不同峰值加速度作用下的動(dòng)力特性、加速度及位移反應(yīng)、開裂及破壞過程做了詳細(xì)分析。試驗(yàn)結(jié)果表明，良好的機(jī)械夯筑性能加上科學(xué)有效的構(gòu)造措施，使現(xiàn)代夯土建筑在遭受相當(dāng)于8度罕遇地震作用下，仍然可以繼續(xù)承載，而且表現(xiàn)出較好的變形能力。現(xiàn)代夯土建筑體系具有一定的推廣與應(yīng)用價(jià)值。［關(guān)鍵詞］現(xiàn)代夯土農(nóng)房; 振動(dòng)臺(tái)試驗(yàn); 地震反應(yīng); 抗震性能中圖分類號(hào)：TU361 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2016)08-0048-05
Shaking table tests on the model of the modern rammed earth house with single-pitched roofZhou Tiegang, Zhu Ruizhao, Song Leshuai, Meng Yaojie(School of Civil Engineering, Xi'an University of Architecture & Technology, Xi'an 710055, China)Abstract: The object of 1/2 scale model of the prototype single-pitched roof house was studied. First, a brief description of the improved technologies of modern rammed earth house was conducted in fields of rammed earth materials, ramming machine, ramming technology and seismic construction measures. Further, the model's dynamic properties, responses of acceleration and deformation, cracking pattern and failure mechanism under different acceleration peak values were discussed in detail. The test results show that good mechanical ramming properties, scientific and effective construction measures make modern rammed earth construction show good bearing capacity and good deformation ability under the rare earthquake equivalent to 8 seismic intensity earthquake. The modern rammed earth construction system has a certain promotion and application value.Keywords: modern rammed earth house; shaking table test; earthquake response; seismic performance
