Assessment of seismic design provisions for multi-tiered ordinary concentrically braced frames
… Special conditions in MT-BFs during nonlinear seismic response lead to concentration of drifts in the tiers and impose additional flexural demands on the columns. These flexural demands, in combination with axial demands, can cause column instability and compromise the seismic performance of …

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 vulnerability assessment of off-ramp structures of the Las Vegas downtown viaduct
… to a strong earthquake were determined using the seismic provisions of the current bridge design codes. In the third stage, non-linear three dimensional finite element models of the off ramp bridges were used to simulate the seismic response of the off-ramp structures to the Sylmar and the ATC …

Response of Cyclically Loaded Extended End-Plate Moment Connections When Used With Welded Built-Up Sections
… Special Moment Frames, as defined by AISC in the Seismic Provisions for Structural Steel Buildings. The experimental results demonstrated that the thick plate procedure in Design Guide 16 is an accurate model for predicting the strength of the connection elements, and the procedure is recommended …

SEITRON SEIsmic elecTRONic handbook : a knowledge based systems approach to structural steel design
… complex with the introduction of new seismic provisions, Clause 27, in its 1989 edition of the Handbook of Steel Design. The implementation of these provisions is meant to provide the necessary ductility and redundancy requirements for the basic types of steel frame construction. Prior …

Effects of residual stresses and initial imperfections on earthquake response of steel moment frames
… methods, the interface between the DM, the AISC Seismic Provisions and the seismic design requirements in ASCE-7 is not fully established. Since the DM, which was developed for design scenarios that do not contain seismic loading, includes the effects of initial geometric imperfections and …

Development and experimental validation of self-centering buckling-restrained braces with shape memory alloy
… significant structural damage to dissipate the seismic energy. The structural damage and the residual drift that may result from the inelastic response can make a building difficult, if not financially unreasonable, to repair after an earthquake. As a result, development of systems that return …

Rational Procedure for Damage Based Serviceability Design of Steel Buildings Under Wind Loads and a Simple Linear Response History Procedure for Building Codes
… in future editions of the NEHRP Recommended Seismic Provisions and ASCE 7. The procedure address the following issues: selection and scaling of ground motions, the use of spectral matched ground motions, design for dependent actions, and the scaling of responses with the response modification …

Nonlinear Finite Element Modelling of Reinforced Concrete Frames Retrofitted with Shape Memory Alloy Buckling Restrained Braces
… buildings built prior to the enactment of modern seismic provisions are vulnerable when subjected to high-magnitude earthquakes since they lack the capacity to properly dissipate the energy associated with the ground excitation. Therefore, this research aims to investigate the benefits of …

Performance of Full-Scale Reinforced Concrete Columns Subjected to Extreme Earthquake Loading
… to investigate their performance under extreme seismic events that would produce near-collapse conditions. One of the goals of the tests was to investigate any potential differences in performance with column size, thus, the test specimens were larger than nearly all of the columns tested …

Inelastic behavior and seismic collapse prevention performance of low-ductility steel braced frames
Seismic-force-resisting systems (SFRSs) in areas of low and moderate seismicity such as the east coast of the United States have minimal ductility. Unlike high-ductility systems, whose design encompasses extensive seismic detailing and proportioning requirements to provide said ductility, the …

Seismic experimental analyses and surrogate models of multi-component systems in special-risk industrial facilities
… of damage following recent major/moderate seismic events and numerical/experimental studies, it clearly emerges that critical non-structural components (NSCs) that are ubiquitous to most industrial facilities are particularly and even disproportionately vulnerable to those events. …

Assessment of modeling sensitivity for nonlinear seismic analysis of highway bridges in Illinois
… Highway and Transportation Officials (AASHTO) seismic provisions were updated in 2008. These provisions increased the design earthquake return period from 500 to 1000 years, eventually demanding special structural systems to counteract seismic forces and therefore increasing construction costs. …
