换流阀 有限元分析 抗震设计
2010/8/17
建立换流阀有限元模型建立，运用有限元分析方法对云广工程换流阀进行模态分析，结果表明：采用悬吊结构设计的换流阀在地面水平加速度峰值0.25g，地面垂直加速度峰值0.15g的地震波作用下是安全可靠的，云广工程换流阀设计满足抗地震要求。
One of the main problems that occurre in the designing process of steel structure is the achieving of a proper connection. By the means of ductility, similar to the case of structures, connections are...
Seismic design force for single-span slab-girder skewed bridges
Skewed bridge slab-girder seismic analysis cross-frame elastomeric bearing
2009/2/20
This paper investigates the validity of seismic design force recommended by AASHTO for single-span bridges. The prescribed force is equal to the products of soil factor , acceleration and tributary we...
In design of conventional bridges the gap between bridge spans is usually only a few centimetres. For such an expansion joint poundings between adjacent bridge girders during strong earthquake shaking...
A STUDY ON FORCE-DISPLACEMENT-BASED SEISMIC DESIGN OF SINGLE-COLUMN RC PIERS
acceleration-displacement response spectrum modified Park-Ang damage index
2008/12/29
As a fundamental study to develop a force-displacement-based seismic design of RC piers, the acceleration-displacement response spectrum (ADRS) of SDOF systems with elastic-plastic bilinear restoring...
TWO-LEVEL SEISMIC DESIGN METHOD USING POST-YIELD STIFFNESS AND ITS APPLICATION TO UNBONDED BAR REINFORCED CONCRETE PIERS
post-yield stiffness two-level seismic design UBRC structure small section pier
2008/12/22
The two-level seismic design method using post-yield stiffness is proposed. The post-yield stifiness on the load —displacement relationship of the RC pier is found to be effective for the reduction o...
