抗震设计的非线性分析方法一个相对简单的非线性结构抗震分析（N2方法）方法。它结合了静力弹塑性分析多度的自由度（MDOF）以及等效单自由度的自由度（SDOF）系统的响应谱分析模型...
近海岸结构平台大部分由圆形管节点组成，它们有个低风阻系数，很好的强度质量比，没有优惠屈服方向等优点。管结构的节点如图1所示。然而这些节点由于很高的应力集中、固有的焊...
abstractAlthough concrete is a non-combustible material, it is found that when exposed to high temperatures,uch as fire, the physical, chemical and mechanical properties of concrete can drastically change. Thus,t becomes important to assess...
AbstractThis paper presents a global analysis approach to the calculation of the natural frequencies of asymmetric, three-dimen-sional frame structures in which the primary frames run in two orthogonal directions and whose properties may var...
Elastic buckling and second-order behaviour of pitched-roof steel frames Abstract Department of Civil Engineering and Architecture, ICIST/IST, Technical of Lisbon Abstract The aims of this work are two-fold: (i) to present the results of a...
AbstractThe paper describes a two-step finite element formulation for the thermo-mechanical non-linear analysis of thebehaviour of the reinforced concrete columns in fire. In the first step, the distributions of the temperature over thecr...

Abstract: This paper presents the analysis of a steel connection. The analysis is performed using solid finite element and is compared to the experimental test performed in the laboratory. During the analysis special attention should be paid...
Dynamical Formulation and Analysis of double crank ring-plate-type pin-cycloidal gear planetary drive Keywords: Mechanical Transmission; pin-cycloid drive; double crank ring-plate-type pin-cycloidal gear planetary drive; dynamical analysis;...
Basic Machining Operations and Cutting Technology Abstract Machine tools have evolved from the early foot-powered lathes of the Egyptians and John Wilkinsons boring mill. They are designed to provide rigid support for both the workpiece and...
