In order to evaluate repairability (i.e., repair time and cost, etc.), it is necessary estimate the amount of labor (person-day) for caused by seismic damage. The purpose this study obtain fundamental information establishing relation model between L per unit floor area inter-story drift angle R L-R model). We analyze effects structural non-structural components failure mode members, on relatio...

STOCK DEFINITION AND GEOGRAPHIC RANGE Hawaiian monk seals are distributed throughout the Northwestern Hawaiian Islands (NWHI) in six main reproductive subpopulations at French Frigate Shoals, Laysan Island, Lisianski Island, Pearl and Hermes Reef, Midway Atoll, and Kure Atoll. Small subpopulations also exist at Necker Island and Nihoa Island and a few seals are distributed throughout the main H...

STOCK DEFINITION AND GEOGRAPHIC RANGE Hawaiian monk seals are distributed throughout the Northwestern Hawaiian Islands (NWHI) in six main reproductive subpopulations at French Frigate Shoals, Laysan and Lisianski Islands, Pearl and Hermes Reef, and Midway and Kure Atoll. Small numbers also occur at Necker, Nihoa, and the main Hawaiian Islands, primarily at Niihau. Genetic variation in Hawaiian ...

The effect of different combinations of response feedback on the performance of active control system on nonlinear frames has been studied in this paper. To this end different feedback combinations including displacement, velocity, acceleration and full response feedback have been utilized in controlling the response of an eight story bilinear hysteretic frame which has been subjected to a whit...

High-rise buildings subjected to lateral loads such as wind and earthquake loads must be checked not to exceed the limits on the maximum lateral displacement or the maximum inter-story drift ratios. In this paper, a sensing model for deformed shapes of a building structure in motion is presented. The deformed shape sensing model based on a 2D scanner consists of five modules: (1) module for acq...

The effectiveness of Metallic dampers for seismic response reduction of structures is quite well known in the earthquake engineering community. However, little attention has been paid to evaluating the influence of the number and placement of this type of dampers on the dynamic response. Using genetic algorithms as an optimization technique will allow for the simultaneous number and design of a...

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...

Pada perencanaan struktur gedung, perhitungan beban lateral akibat gempa sangat diperlukan. Analisis respons spektrum adalah cara analisa hubungan antara periode bangunan dengan nilai percepatan ketika terkena gempa. Analisa statik ekuivalen biasa digunakan pada yang tidak terlalu tinggi, dimana pengaruh dianggap sebagai horisontal pergerakan tanah. Penelitian ini menggunakan objek gedung perku...

The effect of aftershocks on the fragility single-story masonry structures is investigated using probabilistic seismic demand analysis Finite element models an unreinforced (URM) structure and a confined (CM) are established their response characteristics when subjected to mainshock, aftershock, mainshock-aftershock sequence then comparatively investigated. effects use confining members studied...

Near-fault ground motions have caused very much damage in the vicinity of seismic sources during recent earthquakes. It is well known that under specific circumstances, intensive ground shakings near fault ruptures may be characterized by short-duration impulsive motions. This pulse-type motion is generally particular to the forward direction, where the fault rupture propagates towards the site...
