Abstract: A new method of connecting members, at certain joints of a lateral force resisting structure, improves the response to seismic excitation. These connections that permit a small initial slip (displacement or rotation) are ...

Abstract: Numerous concepts have been considered, and are still being developed, for permanent lunar base structures. These concepts try to account for the lunar environment and its particular requirements. Among other parameters, ...

Abstract: Nonuniform seismic motion affects the seismic behavior of long-span bridges. Three main reasons for this nonuniformity have been identified. They are local soil conditions, wave passage, and incoherency effects. Other ...

Abstract: Lunar environmental characteristics, such as the lack of atmosphere, the smaller gravitational acceleration, and the weaker regolith, place different requirements on structural systems than the earth environment does. Some ...

Abstract: The design and construction of public buildings to provide life safety in the face of explosions is receiving renewed attention from structural engineers. Existing blast design approaches call for modest enhancements in ...

Abstract: One of the most frequently used approaches for minimizing the potential for progressive collapse in buildings is the alternate path method. The appeal of this method is primarily due to its relative simplicity and threat ...

Abstract: This paper examines the behavior of steel moment frames under the scenario of a column removal at their ground floor. Through a material and geometric nonlinear analysis, this work evaluates a global loss-of-stability ...

Abstract: An analysis method to quantify the alternate load paths (ALPs), inspired by the concept of ALP for progressive analysis of buildings, is proposed for steel truss bridges subject to the loss of a critical member. Quantification ...

Abstract: We present an overview of the analysis and design of mitigation schemes for buried structures subjected to impact loading, with a focus on the hazard evaluation to underground utilities from ...

Abstract: This study proposes an integrated and easily applicable framework that considers the dynamic effect of sudden member loss to identify the critical members in steel truss bridges through nonlinear dynamic analysis. Numerical ...
