建築物的祖龕、斗拱、橫梁、檐板及墻頭均飾有精緻的木刻、彩塑及壁畫，圖案的題材均寓意吉祥，充份反映了昔日工匠的精湛技藝。Based on extensive investigation of construction technique history of chinese ancient buildings, the structure method, structure developing history and seismic behavior of chinese ancient timber structure buildings are analyzed in several respects of the structural system and form. through a series of experiments on constituent parts of chinese ancient timber building structure, including the tests on the corbels and brackets called dougong subjected to low cyclic reversed loadings, the tests on the wooden frame using the tenon - mortise joints as connections of column and beam subjected to low cyclic reversed loadings, the tests on vibration isolation effect of friction and slippage between column footing and their socle base, and a series of shaking table tests on a chinese ancient timber structure palace building mode under artificial earthquake at serving conditions, destroyed conditions and reinforced conditions, many valuable results of structures such as moment - curvature hysteretic loops of dougong structure and tenon - mortise joints under low cyckc reversed loadings, the static function, the seismic performance, energy dissipation, vibration reduction, energy - loss mechanism, nechanicalmode and failure mode were studied. aplenty of valuable parameters of the structure system were obtained, such as the natural period of structure, vibration modes, damping ratio, factor of vibration isolation, oscillate amplitude of ineitial accebration, velocity and displacement, magnitude of slippage, and the mechanism of structure failure and collapse etc. based on these research, the complete analysis of ancient timber structure under earthquake were carried out in which including mechanism analysis method, calculating mode, strength analysis of members and joints, strengthening methods for serving damaged ancient timber structure buildings were also taken into account
依照宋代《營造法式》建造了抬梁式殿堂木結構構件及結構模型，對中國古代木結構中的典型構造如：柱腳在礎石頂面平擱簡支、柱架榫卯連接、柱高不越間之廣、側腳、生起、斗拱等的構造機理及結構功能進行了量化分析和實驗研究： （一）通過木柱石礎靜摩擦試驗，測定了柱腳與石礎古鏡面間的摩擦系數及摩擦力隨上部結構荷載變化的規律； （二）通過單柱承載力試驗，測定了古建築中木柱的受力變形特徵、破壞模式、及模型材料的變形模量、極限承載力、極限變形等參量； （三）通過柱架低周反復荷載試驗，測定了柱架的抗側移剛度、柱架恢復力特性及滯回曲線、榫卯張角剛度及其變化規律、柱架及榫卯的極限承載力和極限變形、及榫卯減振參數； （四）通過斗?低周反復荷載試驗和受壓試驗，測定了古建築木構件與木構件間摩擦系數，斗?抗側移剛度，斗?恢復力特性及滯回曲線，斗?抗壓極限承載力及受力變形規律； （五）通過抬梁式殿堂間架模型振動臺試驗，測定了殿堂木構架結構自振周期，地震反應振形、阻尼特性及阻尼比；按結構分層特點對柱腳、柱頭和斗?層上的屋蓋的地震反應採用多點同步測量，對柱根滑移、榫卯變形、斗?的變形、復位、耗能減振參數等進行了定量分析。We consider each sleeper as an abutment of opposite forces, rails on horizontal sleepers as a mock dispersed elastic ground beam model and trains as moving load on beams. geometric roughness and damping are not taken into consideration
將每根枕木考慮成一個支座反力，將橫向枕木支承的鋼軌模擬成離散的彈性地基梁模型，將列車考慮成一個作用在樑上的移動荷載。The major research of this paper is that : 1, it is analyze the displacement response of the elastic - foundation beam by the static loads and the moving loads, the dynamic response of winkler beam, analyze the influence of the sleeper in the dynamic response of the rail system. and compare the result with the experiment formulation. it is concluded that the continuous model only fit for the lower moving velocity of loads
本文主要進行了以下幾方面的研究： 1 、首先對靜力荷載作用下彈性地基梁的位移反應、文克爾梁模型的動力響應，及枕木在軌道系統動力響應中的作用進行了分析，並與傳統採用的經驗公式進行對比，以此分析了連續性模型只適用於荷載移動速度較低的情況下，在速度較高的情況下，特別是接近臨界速度時，連續性模型是無效的。分享友人
