Performance Assessment of Reinforced Concrete Structural Walls for Seismic Loads
The performance of each building was evaluated by calculating the confidence level. The results showed a good performance of RC shear wall buildings designed by current provisions. As a result, the buildings were redesigned using higher R-values, and the performance evaluation procedure was …

Performance Evaluation of Cold -Formed Steel Braced Frames for Seismic Loads
A series of 2-, 4- and 6-story buildings were designed and evaluated using the proposed method. It was found that 4- and 6-story buildings design and configured based on current provisions using an R factor of 4 did not satisfy the design objective. This resulted mainly from excessive drift demands …

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 …

Wedge failure analysis of anchored rock slopes subjected to surcharge and seismic loads
… the wedge failure subjected to surcharge and seismic load has not yet been studied in detail in earlier studies. In this thesis, the rock slope subjected to the generalized loads such as surcharge and seismic/dynamic loads is analyzed against the wedge failure by the limit equilibrium method. …

Performance Prediction and Evaluation of Low Ductility Steel Moment Frames for Seismic Loads
… the 20-story building with WCSB configuration in Seismic Design Category C collapsed due to story mechanism and high P-Delta moments. Therefore, it is recommended that WCSB design be restricted to 120 feet tall. All of the buildings with T-stub connections performed well except for the 3-story …

Nonlinear dynamic analysis of wind turbine towers subject to design wind and seismic loads
… failures due to very strong wind and/or seismic loads. Such loads, if not properly addressed, may result in excessive deformations which, in turn, may cause significant damage, or even collapse of wind turbines. This research proposes the development of a novel nonlinear dynamic response …

Stability analysis of anchored rock slopes against plane failure subjected to surcharge and seismic loads
… are several parameters including surcharge and seismic loads that govern the stability of the rock slope against plane failure in field projects. The limit equilibrium approach for the estimation of the factor of safety of the rock slope against plane failure has been well accepted by the …

Effect of Hysteresis Type on Drift Capacity for Global Collapse of Moment Frame Structures for Seismic Loads
… behavior in moment frames subjected to seismic loads may lead to different levels of response because of degradation in strength and stiffness. To examine the existence and magnitude of this effect, this research aims to: (1) Determine the global collapse capacities of several classes of …

A comparative study : the dynamic behavior of tall buildings with diagrid and hexagrid structural systems subjected to seismic loads
… efficiency by resolving both gravity and lateral loads with the same elements. A new iteration of such tubular shell system named hexagrid was examined in this paper. The aim of the study is to evaluate the dynamic response and behavior of such systems when they are subjected to seismic loads, and …

Finite Element Analysis of the Application of Synthetic Fiber Ropes to Reduce Seismic Response of Simply Supported Single Span Bridges
Movement of a bridge superstructure during a seismic event can result in damage to the bridge or even collapse of the span. An incapacitated bridge is a life-safety issue due directly to the damaged bridge and the possible loss of a life-line. A lost bridge can be expensive to repair at a time when …
