Adaptive Space Frame Analysis: Part I, a Plastic Hinge Approach
This is one of two companion papers presenting new procedures for the efficient largedisplacement analysis of steel frames in the elasto-plastic range. Emphasis is given in this paper to the development and improvement of a plastic hinge approach utilizing the concept of adaptive mesh refinement. In the companion paper, such a concept is discussed in the context of a more accurate approach acco...
متن کاملModeling Steel Frame Buildings in Three Dimensions. I: Panel Zone and Plastic Hinge Beam Elements
A procedure for efficient three-dimensional nonlinear time-history analysis of steel framed buildings is derived. It incorporates two types of nonlinear beam elements—the plastic hinge type and the elastofiber type—and nonlinear panel zone elements to model yielding and strain-hardening in moment-frames. Floors and roofs of buildings are modeled using 4-node elastic diaphragm elements. The proc...
متن کاملnon-linear study of various slit shear walls in steel structures
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...

Michael Long, Rice University; Corey Bergad, Bates College; EERC Name: MCEER Host Institution: SUNY at Buffalo Faculty Advisor: Dr. Andrei Reinhorn ________________________________________________________________________ Abstract: A plastic hinge is a type of energy dampening device allowing plastic rotation of an otherwise rigid column connection. This device is composed of a weakened portion ...
متن کاملAnalysis of Thin-Walled Steel Sections Filled with Concrete Using Non-Linear Finite Element Method
Being economical and performing well under cyclic loads, steel sections filled with concrete have been widely used in structural buildings. Extensive studies and experiments have been conducted to investigate the influence of different parameters and loadings on the behavior of these structural components. Based on the data available from previous experiments and studies, this paper discusses t...
