The response of architectured structures is characterized by multi-scale kinematics, which complex relation and effect on the engineering load still not completely understood therefore needs further investigations. More precisely, lack experimental methods enabling to provide data remains a key issue. paper presents an numerical analysis crushing tests performed thin-walled auxetic metallic lat...

In this study, impacts of residual stress and shear deformation are investigated on 2D steel frames using a new fiber plastic hinge method. Geometry material nonlinearities, stress, deformation, imperfections considered simultaneously in the nonlinear analysis. The proposed method is efficient computational efforts since one-element modeling used for analysis by employing stability functions ca...

past earthquakes have demonstrated that old rc bridges may be seismically vulnerable. bridge responses during the last decades illustrated the necessity of the seismic assessment of bridges especially those which were designed with old codes. in this research an existing concrete bridge representative of the most common bridges in the highway system in iran are studied. push over and nonlinear ...

the objective of this review to be submitted in two independent parts, for steel frames and for rc frames, is to compare their structural performance with respect to the proposed n2-method, and so also of the consequent convenience of using pushover methodology for the seismic analysis of these structures. a preliminary investigation is presented on a pushover analysis used for the seismic perf...

To analyze the multidimensional elastic–plastic response of frame structure with magnetorheological (MR) dampers under strong seismic excitations, test MRD was performed, location matrix in derived, and calculation models without an were established based on three-segment variable stiffness beam. Taking a five-story reinforced concrete (RC) as example, developed by MATLAB software dynamic time ...

With the development of plastic surgery techniques, computer aided approach has become a significant method in medical plastic surgery. In order to solve effects on surgical results made by the surface of a wound in craniofacial cosmetic surgery, accurate preoperative preparation is usually required for the surgery. This paper summarizes the application of computer aided technology in craniofac...

Abstract M oment R esisting (MR) einforced C oncrete (RC) frame system presented in the current seismic design standards and required to on-site action develops soft storey mechanisms. In practice, idealized theorized ductile response specified for this structural type does not occur. these conditions, research study presents a logical scheme regarding development method of MR RC system. The ma...

The primary seismic force-resisting system (SFRS) in middle- to high-rise reinforced concrete (RC) building structures often includes coupled shear walls (CSWs) and single (SSWs). These are designed transfer lateral forces the foundation dissipate energy through development of plastic hinges. latter lead residual displacement these structural components. On other hand, self-centering systems en...

Thin-walled tubular structures are widely used in industries such as automotive, aerospace and military because of their lightweight excellent performance under different loading conditions. This study aimed to investigate the lateral crushing square aluminium tubes filled with cores (honeycomb, polyurethane foam mixed these two fillers). Different failure modes tested have been observed they p...
