Effect of seismic loading on steel moment resisting frames
In recent history, the use of Steel Moment Resisting Frames (SMRF) in many structural steel buildings has become popular among many engineers and designers. The use of these moment resisting frames allows for more open spaces between floors and columns than in buildings that use the more …

Design of moment end-plate connections for seismic loading
Analytical and experimental research into the seismic response of four-bolt extended moment end-plate connections was conducted. Full-scale connections, ranging in size from moderate to large, were designed, fabricated and tested under cyclic loading until connection failure was observed. The …

Evaluation of Extended End-Plate Moment Connections Under Seismic Loading
… end-plate moment connections subjected to cyclic loading. Seven specimens representing three end-plate moment connection configurations commonly used in the pre-engineered building industry were used. The connections were designed using yield-line theory to predict end-plate yielding and the …

A web-controllable shaking table for remote structural testing under seismic loading
… may upload their own input data, such as the seismic ground acceleration of a newly occurring earthquake, and therefore study the corresponding behavior of a real structure. The system is designed with an expandable architecture which enables future researchers to add functionalities that suit …

Modelling the Post-Peak Response of Existing Reinforced Concrete Frame Structures Subjected to Seismic Loading
… designed according to older, less stringent seismic codes are often vulnerable to shear or flexure-shear failure followed by axial failure. Thus, such substandard R/C structures are susceptible to vertical collapse, which pertains to the exceedance of vertical resistance of columns and …

Impacts of lateral code changes associated with the 2006 International Building Code and the 2008 California Building Code
… to the procedure to determine earthquake design loading, and a drastic move to a complicated method to determine design wind pressures. The implementation of the revised 2006 International Building Code, and the subsequent California adoption of the structural section will have significant …

A Numerical Investigation of the Seismic Response of the Aggregate Pier Foundation System
… of an aggregate pier foundation system during seismic loading was investigated. The factors and phenomena governing the performance of the aggregate pier and the improved ground were identified and clarified. The key factors affecting the performance of the aggregate pier include soil density, …

Evaluation of Failure Mechanics of the Malpais Landslide, Eureka County, Nevada
… an increase in the water table level and/or seismic loading, given the proximity to the Malpais and other faults that have documented Holocene movement. The Malpais landslide failure depended on the presence of very weak lacustrine sedimentary units, and similar weak units are present at …

Implications from a geotechnical investigation of liquefaction phenomena associated with seismic events in the Charleston, SC area
… in the Charleston area due to recurring large seismic events. Although this information has led to an improved understanding of seismicity in the Charleston region, little hard data exists in terms of ground motion characteristics or levels of seismic loading. A two-year field investigation was …

Stochastic Analysis of Seismic Safety Against Liquefaction
… of the strong-motion duration of a random seismic loading with a given intensity that causes liquefaction. These statistics are used to define the seismic resistance curves against liquefaction in the deposit. It is assumed that liquefaction occurs when the excess pore pressure becomes …

A performance-based approach to retrofitting unreinforced masonry structures for seismic loads
… masonry (URM) buildings to resist possible seismic loading is a serious problem in many parts of the United States, including the Northeast and Midwest. The fact that many of these buildings are deemed historic structures or house critical facilities, like firehouses, emphasizes the need for …

Quick methods of analysing earthquake forces on viaduct bridges having continuous decks and tall piers
… obtained by manual calculation. The earthquake loading effects are compared with the effects of deadload, traffic loading and windload and there is a discussion on the design of suitable structural configurations to contend with seismic loading. The work ends with some generalisations about …

Application of the Finite Element Method to the Seismic Design and Analysis of Large Moment End-Plate Connections
… a much more attractive alternative for design in seismic regions. However, stringent design requirements established by the AISC Seismic Provisions for Structural Steel Buildings (1997) make current moment end-plate configurations and design procedures inadequate for multi-story buildings. This …

Seismic Performance of Prestressed Concrete Piles In Cip Reinforced Concrete Pile Caps
… (CIP) reinforced concrete bent caps subjected to seismic loading is not well understood. Current standard SCDOT connection details require the plain embedment of the pile into the bent cap one pile diameter with a construction tolerance of ± 6 inches. To better understand the moment capacity and …
