Estimation of Earthquake Input Energy, Hysteretic Energy and its Distribution in MDOF Structures
… in the earthquake engineering community, is the energy-based approach. In this approach, a design is considered satisfactory if the capacity of a structure to absorb or dissipate energy exceeds its energy demand from an earthquake. In the present research, a new energy-based approach is proposed …

Evaluation of Connection Fracture and Hysteresis Type on the Seismic Response of Steel Buildings
… structure design, the effects of hysteretic energy dissipation on the maximum displacement response amplitude of buildings plays a important role in determining the design forces. Linear, bilinear, strength degradation, stiffness degradation, and connection fracture models were …

Modeling and Analysis of Cyclic Behavior of Sands
… represent the following aspects of behavior: (a) Hysteretic energy dissipation; (b) Accumulated irreversible deformation; (c) Volumetric deformations.

Inelastic seismic behavior of stiffening systems : multi-span simply-supported (MSSS) bridges
… many other damage indices like dissipated hysteretic energy and low-cycle fatigue damage index, it is quite likely that a stiffening system would sustain more damage than an elastic-plastic system. At the end, suitable design response spectra for stiffening systems are developed and their …

Performance-based seismic engineering of low and medium-rise steel frames
… drift, ductility demand, and dissipated hysteretic energy are obtained. In addition, a modified form of Park-Ang damage index is calculated for moment-resisting frames. The seismic performance of the steel frames is assessed in accordance with the acceptance criteria of the NEHRP …

A Framework for Cyclic Simulation of Thin-Walled Cold-Formed Steel Members in Structural Systems
… steel (CFS) framed-buildings supported by hysteretic nonlinear models for CFS members and screw-fastened connections. Design of CFS structures subjected to lateral seismic forces traditionally relies on the strength of subassemblies subjected to lateral loading of systems, such as …
