Currently, the seismic collapse risk of modern code-conforming reinforced concrete (RC) frame structures is often evaluated without considering behavior beam-column (BC) joints since designed to meet design codes are assumed be sufficiently rigid. BC in RC ductile moment frames may undergo a significant amount inclined cracking during strong earthquakes. Consequently, stiffness, strength, and d...

This study investigates the potential seismic risks of double fab structures uniquely seen in Taiwan’s semi-conductor industry. A typical eight-story double fab structure is considered as the object to explore the seismic vulnerability of such structural systems via computer simulation under realistic earthquake ground motion. As expected, excessive storydrifts are found to be focused on the cl...

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...

Fault, crushed zone, and other unfavorable geology may frequently appear in the construction of tunnels, so it is course necessary to study on dynamic properties tunnels crossing rock fracture zone. Taking tunnel faults as object, this paper discussed constitutive relation satisfied by structures researched loading features failure characteristics different faults. It shows that: (1) areas with...

nonlinear static procedure (nsp) is a common technique to predict seismic demands on various building structures by subjecting a monotonically increasing horizontal loading (pushover) to the structure. therefore, the pushover analysis is an important part of each nsp. accordingly, the current paper aims at investigating the efficiencyof various algorithms of lateral load patterns applied to the...

distinct target of this paper is development of 'implicit discrete element method (dem)' in three dimensions for estimating the ultimate bearing capacity of shallow foundations on layered (non-homogeneous) soils consisting of sand overlying sand or clay overlying sand and vice versa with different shear resisting parameters. in this method, shear resisting parameters and density of ea...
