    Book Description. Behaviour of Steel Structures in Seismic Areas is a comprehensive overview of recent developments in the field of seismic resistant steel structures. It comprises a collection of papers presented at the seventh International Specialty Conference STESSA (Santiago, Chile, January ), and includes the state-of-the-art in both theoretical and experimental research on. This set of slides covers the fundamental concepts of structural dynamics of linear elastic single-degree-of-freedom (SDOF) structures. A separate topic covers the analysis of linear elastic multiple-degree-of-freedom (MDOF) systems. A separate topic also addresses inelastic behavior of Size: 1MB.

    Figures , and present data for steel reinforcement subjected to reversed cyclic loading. The strain histories used in these material tests are representative of the strain history observed in actual structures. The extent of compressive stress/strain demand is a function of the load history. Annumerical study of RC columns subjected to variable axial load in conjunction with biaxial cyclic bending are presented in this article. The numerical models were built to simulate the response of all specimens using the computer program SeismoStruct and adopting three different modelling strategies, such as lumped plasticity and distributed plasticity (based in displacements and forces.

      Specimens were subjected to reversed cyclic loading according to a prescribed displacement history. Comparisons are made between the behavior of the precast specimens and monolithic specimens. The comparisons are based on connection strength, drift capacity of the connection, and energy dissipation by: 6. A model of hinging behavior in reinforced concrete bridge columns will help guide proportioning, detailing and drift estimates for performance-based design. Data was collected during the NEESR investigation of the seismic performance of four-span large-scale bridge systems at the University of Nevada Reno that details deformations in column.

W.; Stone, William C. To assess such capacity, cyclic loading protocols have been used as a common practice in laboratory and numerical evaluations.

The main objective was to obtain quasi-static loading protocols that reflect the increase in the inelastic demands of bridge columns subjected to long duration ground motions caused by subduction megathrust earthquakes.

The columns were subjected to constant axial load and reversed cyclic lateral displacement to study the influence of the new confinement technique on the lateral strength and ductility of reinforced concrete circular bridge columns as compared to columns confined with a conventional single by: The behavior of concrete filled tube columns under seismic loads was studied through testing six columns which were subjected to a constant axial load in addition to a cyclic lateral load.

An experimental investigation was carried out to study the effect of retrofitting on change in dynamic properties of 1/4 scaled damaged and undamaged bridge piers of low-strength concrete. Response of three bridge piers, subjected to cyclic lateral loads and free vibration tests under constant axial loading, was : Qaiser-Uz-Zaman Khan, M.

a macroscopic model is formulated to predict the cyclic. The inelastic displacement of columns can be increased by shear–flexure interaction (SFI). This paper develops a simple yet reliable demand model for estimating the inelastic displacement and ductility based on the nonlinear time history analyses of 24 full‐size columns subject to a suite of near‐fault ground motions.

Brittle cracks were observed in the welded beam-to-column connections of steel frames during an earthquake. The crack propagation and accumulated damage to the connections can lead to fractures at much lower ductility ratios. Understanding the connections’ damage behavior during an earthquake is crucial for the design of steel moment frames in seismic : Xi-yue Liu, Yuan-qing Wang, Jun Xiong, Yong-jiu Shi.

In slender members, the energy dissipation due to inelastic behavior develops at the plastic hinge region.

The energy dissipation of a plastic hinge can be calculated by integrating the energy dissipation per cross-section over the plastic hinge length.
