According to current design practices of steel moment-resisting frames, formation plastic hinges is unavoidable when the frames are supported by conventional column base systems, i.e., exposed-type and embedded-type due unequalized flexural moment demand on top first story columns [1]. Kimura et.al [3] has proposed mid-story pin system avoid from yielding realize beam-yielding mechanism applyin...

Mid-story pin column system has been proposed to realize beam yielding mechanism of a steel moment-resisting frame. In this system, connection is applied inbetween the upper and lower RC extended from base control moment demands on both ends first story column. An exposed-type adopted as connected by single anchor bolt. Static cyclic horizontal loading tests partial frame consisting second floo...

Wave-propagation effects can be useful in determining the system identification of buildings such as the densely instrumented University of California, Los Angeles, Factor building. Waveform data from the 72-channel array in the 17-story moment-resisting steel frame Factor building are used in comparison with finiteelement calculations for predictive behavior. The high dynamic range of the 24-b...

The unanticipated brittle fracture of connection of the steel moment resisting frame (SMRF) occurred in 1994 the Northridge earthquake. Since then, the researches for the vulnerability of connection of the existing SMRF and for rehabilitation of those buildings were conducted. This paper suggests performance-based optimal seismic retrofit technique using connection upgrade. For optimal design, ...

In this paper, the initiation and propagation of structural damage in a building due to the truck collision to one of its corner columns were investigated. For this purpose, a three-dimensional 4-story moment resisting steel frame with intermediate ductility was considered. The structure was designed using ETABS software under standard dead, live, and earthquake loads, and then impact loading w...

One of the most important problems discussed recently in structural engineering is the structural reliability analysis considering uncertainties. To have an efficient optimization process for designing a safe structure, firstly it is required to study the effects of uncertainties on the seismic performance of structure and then incorporate these effects on the optimization process. In this stud...

This paper describes an experimental investigation into the use of steel bars bonded into glulam timber beams with epoxy resins in order to provide moment-resisting joints between glulam beams and steel supports. The objective of this research was to provide information about the bending and shear strength of such connections. Past research has investigated the use of steel rods epoxy bonded in...

Numerous studies were contemplated on the structures with distinctive structural configuration and ample amount of work is currently being performed through investigation response individual behavior shear walls bracings by varying configurations their material properties. Seismic design philosophies had mentioned firmly that a structure must accomplish Life Safety Performance Level for both re...

This work applies 64,765 simulated seismic ground motions to four models each of 6or 20-story, steel special moment-resisting frame buildings. We consider two vector intensity measures and categorize the building response as “collapsed,” “unrepairable,” or “repairable.” We then propose regression models to predict the building responses from the intensity measures. The best models for “collapse...

Timber-based hybrid structures provide a prospective solution for utilizing environmentally friendly timber material in the construction of midrise or high-rise structures. This study mainly focuses on structural damage evaluation type timber–steel structure that incorporates prefabricated light wood-frame shear walls into steel moment-resisting frames (SMRFs). The such was evaluated through sh...
