首先運用ansys有限元程序分析彈性階段水平外荷載施加后，帶豎縫鋼筋砼空心剪力墻板內應力分佈及變形情況，再在試驗數據的基礎上，研究低周反復水平加載條件下，各試件的強度、變形、能量特性；各試件的荷載特徵值；各試件的滯回曲線、骨架曲線；延性及剛度退化等參數；最後，分析了不同剪跨比和加載條件的帶豎縫鋼筋砼空心剪力墻板的破壞機理和承載力影響因素，並給出不同剪跨比和加載條件的帶豎縫鋼筋砼空心剪力墻板承載力計算公式及設計建議。Then a semi - rigid joint behavior can be modeled as a finite stiffness rotation spring. basing on rotation and displacement equation, we obtain the element stiffness matrixes with semi - rigid connections where the effects of material nonlinear, hysteresis behavior and shear forces in the connection deformations have been considered in and at the same time we modify the fixed - end forces. finally, a program for calculating the elastic - plastic earthquake seismic of semi - rigid connected steel frame structure by step and step integration of wilson -
本文在介紹和分析半剛性連接彎矩與轉角連接關系模型的基礎上，用帶有轉動剛度的彈簧表徵半剛性連接，推導出半剛性連接的剛度矩陣，並對桿件固端力進行修正，同時在考慮剪切變形、材料彈塑性、及構件的動力滯回性能的基礎上，編制了結構彈塑性地震動力時程分析有限元計算程序。In mechanical pressure switches, the form or change in position of a switching membrane, bourdon spring or pressure piston is transferred to one or more microswitches that are integrated into the housing and take over the actual switching operation ; the switching hysteresis is fixed or adjustable
在機械壓力開關中，開關隔膜，波登彈簧或者壓力活塞的形狀或位置改變，轉移到一個或多個集成在箱中的微動開關。這些微動開關事實上接管了開關操作。開關磁滯特性固定或者可調。Under strongly random exterior excitation, most structures will undergo elastic - plastic stage and show hysteretic characteristics, the vibration of structure expresses nonlinear random feature. therefore nonlinear model must be utilized in order to describe the behavior of this kind of structure, also the theory and methodologies of nonlinear random vibration are necessary for analyzing their response
許多工程結構在強烈隨機外激勵下都將進入彈塑性變形狀態，表現出滯后特性，結構的振動表現為非線性隨機振動，因此必須用非線性模型來描述結構，並用非線性隨機振動的理論和方法來進行分析。分享友人
