We present a finite element model updating technique for soil–structure system identification of the Millikan Library building using seismic data recorded during 2002 Yorba Linda earthquake. A detailed (FE) is developed in OpenSees and updated sequential Bayesian estimation approach joint parameter input identification. two-step devised. First, fixed-base structural to estimate parameters (incl...

The cross-laminated timber coupled wall (CLT-CW) system, a recently proposed timber-based structural has limited understanding of its seismic performance. existing research in probabilistic fragility assessment (PSFA) CLT buildings reveals gap, particularly regarding comprehensive evaluation CLT-CW systems and the impact various design parameters. To fully describe state post-earthquake perform...

The excellent seismic performance of concrete-filled steel tube (CFST) structures has been widely recognized, but there is a paucity research on composite columns using UHPC with added fibers. This paper presents the experimental studies and numerical analyses OpenSees ultra-high fiber-reinforced concrete (UHPSFRC)-filled square tubular columns. Five half-scaled specimens UHPSFRC-filled were te...

A finite element model is created using OpenSees software to perform a time history analysis in order analyze the seismic response law of skew bridge and damage volume its key components, typical 3×20 m continuous girder as an example. The under various factors such size abutment expansion joint, shear gap, strength studied then rate assessed for bearing, key, pier. research results show that a...

three unconventional details for plastic hinges of bridge columns subjected to seismic loads were developed, designed, and implemented in a large-scale, four-span reinforced concrete bridge. shape memory alloys (sma), special engineered cementitious composites (ecc), elastomeric pads embedded into columns, and post-tensioning were used in three different piers. the bridge model was subjected to...

this paper describes experimental and numerical investigations on two specimens of frames composed of steel reinforced concrete beam and angle-steel concrete column under horizontal low cyclic loading. based on the test results, the relationship curves of the horizontal load-displacement and the failure modes are acquired. meanwhile the hysteretic behaviors, skeleton curves, stiffness degradati...
