Abstract: Previous research has shown many advantages of the mixed Lagrangian formulation (MLF) for the solution of dynamic problems. In particular, it has shown a very stable and robust behavior with respect to the time step size ...

Abstract: Dynamic simulation of self-centering systems can be computationally challenging due to the opening and closing mechanisms that cause a rapid change in stiffness. In addition, the current modeling of self-centering connections ...

Abstract: High-rise buildings are sensitive to multihazard loads from both short and long-term perspectives. Adding tuned mass dampers (TMDs) is a well-established method to improve the performance of tall buildings, but the ...

Abstract: This paper presents a formal optimization methodology for the damped outrigger problem under stochastic seismic excitations. An efficient analytical model is developed utilizing a Maxwell model connection between the core ...

Abstract: One approach to the optimal design of passive controllers in linear structures for earthquake engineering applications makes use of

Abstract: This paper presents an analysis–redesign-type approach for the efficient seismic design of three-dimensional (3D) irregular RC frame structures for bidirectional ground motions. The designs obtained using the approach ...

Abstract: Past seismic events have demonstrated the vulnerability of suspended ceilings, classified as nonstructural components, to earthquake damage. Engineers, architects, and manufacturers all participate to help ensure that the ...
