this paper examines differences in performances of a range of torsionally stiff and flexible single story buildings designed with the provisions of iranian standard 2800. seismic nonlinear dynamic time history behavior of eight building models subjected to seven horizontal bi-directional design spectra compatible ground motions are investigated. these models cover a wide range of very torsional...

additional dampers are employed in order to decrease the dynamic response of structure against the earthquake and wind loading recently. in this study, two types of systems related to waste of inactive energy, i.e. frictional damper which is categorized in dampers dependent on movement and viscoelastic damper which is categorized in dampers dependent on velocity, in making steel structures resi...

We introduce a novel abstract domain for the safe approximation of continuous functions in the context of abstract interpretationbased static analysis. The key-idea is to represent C + functions by a finite sequence of trapezoids. In this way, we get a strictly more precise approximation of the actual values with respect to existing approaches in the literature. Experimental results underline t...

A definition of progressive collapse is offered and two examples of the phenomenon described. Attention is drawn to potential sources of abnormal loads that should be examined when designing for progressive collapse performance. A plane frame computer program is described for the collapse analysis of reinforced concrete frames using finite elements and a quasi-static approach. The paper conclud...

In order to accurately account for nanometer effects during timing analysis, traditional cell models must be replaced. The assumption of linear input voltages and lumped output load are no longer valid [1]. The existing cell delay models do not match well with the advanced interconnect delay models. Interconnect models consume linear voltage waveforms produced by these cell models and produce v...

this paper presents a novel formulation and numerical solutions for adhesively bonded composite joints with non-linear (softening) adhesive behaviour. the presented approach has the capability of choosing arbitrary loadings and boundary conditions. in this model adherends are orthotropic laminates that obey classical lamination theory. the stacking sequences can be either symmetric or asymmetri...
