The behavior of corroded steel–concrete composite beams under hogging moment was studied by experimental investigation and theoretical analysis. A total of eight specimens, six of which had corroded shear studs, were tested. The corrosion rate of studs ranged from 0 to approximately 50%. The constant-current accelerated corrosion method was adopted to accelerate the corrosion process. The loadi...

Sustainability addresses the need to reduce structure’s impact on environment but does not environment’s structure. To explore this relationship, study focuses quantifying of green roofs or vegetated seismic responses such as story displacements, interstory drifts, and floor level accelerations. Using an archetype three-story steel moment frame, nonlinear time history analyses are conducted in ...

OBJECTIVE Biomechanical effects of laterally wedged insoles are assessed by reduction in the knee adduction moment. However, the degree of reduction may vary depending on the reference frame with which it is calculated. The purpose of this study was to clarify the effect of reference frame on the reduction in the knee adduction moment by laterally wedged insoles. METHODS Twenty-nine healthy p...

fragility curves represent the probabilities that structural damages, under various levels of seismic excitation, will exceed the specified damage states by means of earthquake intensity damage relations. conceptual aspects related to seismic vulnerability, damage and risk evaluation are discussed first, together with a short review of the most widely used possibilities for the seismic evaluati...

The authors propose a design philosophy for steel buildings in moderate seismic regions that draws on familiar concepts of ductility and capacity design, but also integrates the concepts of reserve capacity, elastic flexibility and strength to broaden the field of design possibilities. The paper discusses structural systems representing each of these concepts: Moderate-Ductility Concentrically-...

Abstract This study presents the impact of near-field and far-field earthquakes on seismic design Intermediate Moment Resisting Frame (IMRF) Special (SMRF) structures through FEMA (Federal Emergency Management Agency) P695 methodology to highlight importance probabilistic collapse as well performance factors these structures. The purpose this is investigate steel intermediate special moment res...

Setback irregularities are considered where discontinuity between adjacent stories is excessive. This irregularity caused the probability of high damage at structures subjected to strong earthquake motion. For this purpose, study was conducted by modeling steel special moment frame (SMF) using a finite element calculation program with nonlinear static analysis compared Padang city’s response sp...
