Structures joined by lap-joints can present complex nonlinear dynamic behavior as a function of the stress to which lap-joint is subjected, including contact stiffness variations and softening, along with hysteresis effects related frictional dissipation at interface. Considering applications where use non-parametric models that depend only on input output data required, this work proposes deta...

We study the homotopy relation between the standard 2-local geometry ∆ and the Bouc complex for the sporadic finite simple group McL.

In regions prone to seismic activity, buildings constructed on soft soil pose a significant concern due their inferior performance. This situation often results in considerable structural damage, substantial economic loss, and increased risk human life. To address this problem, study focuses the retrofitting of steel moment-resisting frames using friction metal-yielding dampers, taking into acc...

We study the homotopy relation between the standard 2-local geometry ∆ and the Bouc complex for the sporadic group Co3. We also give a result concerning the relative projectivity of the reduced Lefschetz module L̃(∆).

Topological properties of the matching complex were first studied by Bouc in connection with Quillen complexes, and topological properties of the chessboard complex were first studied by Garst in connection with Tits coset complexes. Björner, Lovász, Vrécica and Živaljević established bounds on the connectivity of these complexes and conjectured that these bounds are sharp. In this paper we sho...

A restoring-force model is a versatile mathematical that can describe the relationship between restoring force and deformation obtained from large number of experiments. Over past few decades, body work on development models has been reported in literature. Under high intensity cyclic loadings or seismic excitations, reinforced concrete (RC) structures undergo wide range hysteretic deterioratio...
