In this paper, attention is focused on the numerical and experimental measurements of seismic response of 3D wall panels surrounded by steel bending frame. The approach of quasi-static cyclic loading is employed using horizontal actuators to the combined system. The displacements in vertical, lateral and horizontal are measured by LVDT equipments. The failure mechanism of 3D wall panels is described in details. The evaluation of strength and stiffness degradation of whole system is presented based on envelope force-displacement curve of actual specimens under cyclic loads. Results of the current study are shown in the form of ductility factors, hysteresis loops and load-displacement envelope curves. The comparison between ductility of sole steel frame, 3D shear wall and combined system as the main theme of the current research is presented. Finally, this work clarifies benefits of using 3D wall panels as a strengthening method for existing of steel frame building and confirms the feasibility resistance of such combined system.

This paper presents a simple axisymmetric 2D finite element analysis using the software, PLAXIS, Version 8, to obtain the response of single pile under vertical vibration. The Mohr-Coulomb model is used for modeling the soil. In the FE model the static load was applied on the top of the pile by introducing the steel plate. A vertical harmonic load was applied in the model to simulate the vibrations transmitted by the oscillator to the pile. Using this model the vertical vibration amplitudes were determined at different frequencies. Vertical vibration tests result of two full-scale single piles are used for the investigation. The tests were carried out in the field with three different eccentric setting and three different static loads. The frequency-amplitude curves obtained from PLAXIS were compared with the experimental results to validate the FE model. It was found that the simple 2D model predict the natural frequency and peak displacement amplitude reasonably well. The variations of amplitude of vertical vibration at resonance along the pile length were also determined by FE model.
