Are uncertain and should be regarded as random variables, therefore the reinforced concrete frame is stochastic structure inherently, and then its motive equations converted to combined random differential equations for the uncertain parameters and external random excitation. these equations were solved by order - orthogonal expansion method with pseudo - excitation method, and then the statistic stochastic responses of random structure were obtained. at last, based on the stochastic cumulative damage model with double parameters developed by park, formulas were formulated for calculating structural earthquake damage probability using the structural reliability theory ( mainly jc algorithm ) in extensive random space
首先對受地震激勵的剪切型鋼筋混凝土結構進行建模，用隨機等效線性化方法將二階非線性微分方程組化成一階線性微分方程組（或稱之為狀態方程） ；再考慮材料等參數的隨機性，則狀態方程成為復合隨機微分方程組，將擴階系統方法和虛擬激勵方法推廣並應用於這個復合隨機微分方程組，求出結構的隨機響應量的統計參數；最後採用隨機累積損傷破壞準則，在廣義隨機空間內，用jc演算法求解失效概率，進而求出結構的抗震可靠度。 -
This paper, in allusion to damage of expansion joint of bridge, introduces a sort of new structure of jointless device - semi - integral abutment jointless bridge, and establishes model of general structure finite element of this bridge, and in details analyses its qualities of stress. the model considers the interaction of superstructure - substructure - soil. resistance of the soil behind abutment adopts still soil pressure and elastic resistance when the temperature rising, but active soil pressure when dropping. analysis of qualities stress of bridge includes of action of dead load, car load, temperature load of season character. taking an 100m length pc semi - integral abutment jointless bridge as instance, the paper establishes the model of plane frame by applying large common software - anasys, and analyses it by elastane and large deformation to imitate character of stress and deformation of general bridge. at the same time corresponding models of finite element of joint bridge and integral abutment bridge are established, and unique stress and performance of structure of semi - integral abutment jointless bridge are researched by comparing and analysing character of three different models under same loading, and controlling factor of design and constitution are generalized. in conclusion, for semi - integral abutment jointless bridge, on one hand shear, moment and deflection of the main beam and axis force of substructure are approximate with that of joint bridge, and integral stifmess of structure is increased and damage of expansion joint is eliminated, on the other hand there is axis force in main beam, shear and moment of substructure are bigger than that of joint bridge. in all this type of jointless bridge has rational stress and is worth of application and popularization
半整體式橋臺無縫橋梁計算模型考慮了上部結構-下部結構-土的共同作用；臺後土抗力升溫時採用靜止土壓力加彈性土抗力，降溫時採用主動土壓力；分析橋梁受力性能時考慮了結構自重、車輛荷載和季節性溫變荷載的作用。以一座橋長100mpc半整體式橋臺無縫橋梁為實例，採用大型通用軟體ansys建立平面框架模型，進行彈性、大變形分析，模擬全橋受力和變形特點；同時建立與此對應的有伸縮縫橋梁和整體式橋臺無縫橋梁有限元模型，通過三種橋型同步加載對比分析，研究半整體式橋臺無縫橋梁獨特的受力特點和結構性能，總結其設計控制因素和構造要求。通過本文研究知：半整體式橋臺無縫橋梁主梁的剪力、彎矩、撓度和下部結構的軸力與梁式橋相近，結構整體剛度增大，併除去了伸縮縫病害；但主梁增加了軸力，下部結構剪力、彎矩較梁式橋大；綜合分析是一種受力合理有實踐和推廣價值的橋型。 -
The pc rigid frame bridge can meet with the carrying capacity of long span bridge. this kind of structure is fit for the comfortable steer with no other expansion joints except for those at the two ends. it characterized the wholeness of structure, good astigmatic ability and load - bearing ability, construction rapidness, bright and pithiness bridge style, easy to maintain and convenient for segmental construction using the cantilever technique, so rigid frame bridge have taken an increasingly great proportion in bridges constructed and those under construction at city and county
