The high storey building structure is modeled as an equivalent cantilever beam on nonlinear supports.Its governing equations are derived by using the Ritz method, eigenfunctions of cantilever Euler-Bernouli beam being used as the Ritz vectors.Since the number of degrees of freedom in the Ritz space is much fewer than that in a finite element method, the computational work can be reduced considerably. This method can be used to analyze shear wall structures with elasto-plastic hinges or dampers as...

The high storey building structure is modeled as an equivalent cantilever beam on nonlinear supports.Its governing equations are derived by using the Ritz method, eigenfunctions of cantilever Euler-Bernouli beam being used as the Ritz vectors.Since the number of degrees of freedom in the Ritz space is much fewer than that in a finite element method, the computational work can be reduced considerably. This method can be used to analyze shear wall structures with elasto-plastic hinges or dampers as well as tall frame-type structures. Numerical results show that the seismic response of a building structure can be reduced significantly by using to nonlinear and strong dampers.

将高层建筑结构近似地等效成非线性弹性支承梁,以悬臂梁、柱之本征函数作为Ritz矢量,用能量法推导出结构的运动方程,其自由度数及计算量均比用有限元法时大为减小。用本文的方法可以计算具弹塑性铰或弹塑性耗能器之剪切墙及框架式高层建筑结构。计算结果表明,采用非线性耗能器并引进高阻尼,可以显著地降低结构之地震响应。

In this paper nondestructive damage detection (NDD) in large/complex structures is investigated based on vibration monitoring. A new method of damage detection is presented, which utilizes an invariance property of element modal strain ener gy. The theory of NDD for frame type structure is formulated. This method is ba sed on assigning element modal strain energy to two parts, and defines two damage detection indexes. One is compression modal strain energy change ratio (C MSECR), the other is...

In this paper nondestructive damage detection (NDD) in large/complex structures is investigated based on vibration monitoring. A new method of damage detection is presented, which utilizes an invariance property of element modal strain ener gy. The theory of NDD for frame type structure is formulated. This method is ba sed on assigning element modal strain energy to two parts, and defines two damage detection indexes. One is compression modal strain energy change ratio (C MSECR), the other is flexural modal strain energy change ratio (FMSECR). The pr esent modal strain energy are obtained by incomplete modal shape and structural stiffness matrix. Structure health monitoring is thus accomplished via monitorin g the elemental CMSECR and FMSECR. Several damage cases are simulated with an of fshore platform numerical model (FEM), and presented to illustrate the utilit y of the proposed method. According to the results, the proposed method is shown to be effective for the complex structural damage detection and has satisfactor y precision.

针对海洋平台等复杂大型土木工程结构物 ,研究基于振动测试的无损检测方法 ,提出了一套利用结构单元模态应变能特性的新损伤诊断方法。该方法是将结构单元的模态应变能分解为拉压模态应变能和弯曲模态应变能 ,并定义了两个损伤诊断指标 ,即拉压模态应变能变化率 (CMSECR)和弯曲模态应变能变化率 (FMSECR)。模态应变能是通过结构不完备模态振型和结构刚度矩阵计算出的 ,因此 ,可以通过振动测试得到结构单元的两个损伤指标诊断结构的损伤。为了验证本文所提出损伤诊断方法的正确性 ,利用海洋平台有限元模型数值模拟了三个典型的损伤工况。根据损伤诊断结果 ,本文所提方法能够得到较满意的诊断精度 ,具有一定的实际应用价值

The S02-10 battery tractor with an automatic dragging system is launched through retrofitting the firstly developed S01-10 battery tractor.The S02-10 uses the S01-10 hydraulic steering system,adds lifting cylinder to truck body tail,and redesign the dragging system,which features frame type structure,and use slip block and slip way to help dragging hook realize lifting function and thus automatic hook engagement.This paper presents automatic hydraulic dragging system design.

在已经研制第1台蓄电池式牵引车S01—10的基础上,推出了S02—10蓄电池式牵引车,增加自动拖挂装置。它利用原车的转向液压系统,在车体尾部增加液压升降缸,重新对拖挂装置整体结构进行设计,采用框架式结构,通过增加滑块和滑道,辅助配合拖挂钩进行升降,实现自动挂钩。本文主要介绍自动拖挂液压系统设计。
