The disscussions on the characters of earthquake response, such as structure displacement, action of earthquake, the amplificatory coefficient of acceleration and the rule of strain were made 討論了結構各樓層的水平位移、地震力、加速度放大系數(shù)及構件應變分布等結構地震反應特征。
The pseudo-dynamic test of 1 / 3-scale model six-story building assembled with hollow shear wall with seams . the internal forces, the deformation and the failure mechansm of the building under earthquake are studied . the rules of frequency, damping and response spectrum are studied . the characters of earthquake response such as structure displacement, interstory drift, action of earthquake, the amplificatory coefficient of acceleration and the rule of strain are discussed . at last, this paper presented the design method of this structure based on the aseismic style and put forward the construction 進行了帶縫空心剪力墻結構六層樓房的13模型的擬動力試驗,研究了結構在水平地震作用下的受力特點、變形特征、破壞形態(tài)等力學性能;得到了結構在不同受力階段的頻率、阻尼、反應譜等動力特性變化規(guī)律;討論了結構各樓層的水平位移、層間位移、地震力、加速度放大系數(shù)及構件應力分布規(guī)律等結構地震反應特征;指出了結構的抗震類型、薄弱層及薄弱部位;提出了多層帶縫空心剪力墻結構的第一階段設計方法和相應構造措施。
2 . dynamics analysis : by setting up jacon matrix differential coefficient sport is passed to descartes space . it makes terminal executing manipulator produce differential coefficient of acceleration and force in every different coordinates can be got . then the effective inertia, coincident inertia and gravity load of two manipulators are calculated by lagrange method . so generalized joint torque of each joint is got, and along with equivalent driving torque, actual driving torque of each joint can be worked out . 3 動力學分析:建立雅可比矩陣將關節(jié)空間的各關節(jié)的微分運動傳遞到笛卡爾空間,使末端執(zhí)行器位姿產生微分運動,以用于求加速度及力在不同坐標系間的線性變換,再用拉格朗日法計算兩機械手的有效慣量、偶合慣量、重力載荷,從而計算得到各關節(jié)的廣義關節(jié)力矩,并與等效驅動力矩共同算得各關節(jié)的驅動力矩。
