  • Modal Identification Of A Tested Steel Frame Using Linear Arx Model Structure 

    Kaya, Yavuz (Islamic Azad University, South Tehran Branch, 2009-07-01)
    This study contains the identification of modal dynamic properties of a 3-story large-scale steel test frame structure through shaking table measurements. Shaking table test is carried out to estimate the modal properties ...

  • Analysis Of Reinforced Concrete Hollow Piers Behavior: Benefits Of Frp Confinement 

    Lignola, Gian Piero؛ Prota, Andrea؛ Manfredi, Gaetano؛ Cosenza, Edoardo (Islamic Azad University, South Tehran Branch, 2009-07-01)
    Reliable stress-strain behavior of concrete is necessary particularly when a member is subjected to combine bending and axial load and confinement effects should be accounted for. A unified theory for confinement of circular ...

  • Hysteretic Dissipators Made Of Aluminium And Steel: Optimal Design And Preliminary Characterization Tests 

    Diaferio, Mariella؛ Foti, Dora؛ Nobile, Riccardo (Islamic Azad University, South Tehran Branch, 2009-07-01)
    In this paper the optimal design of a dissipator made of aluminium and steel and principallysubjected to shear forces and the preliminary results of the characterization tests are described.The device has been ...

  • Seismic Assessment And Strengthening Of An Existing Steel Bridge In Portugal 

    Fernandes, Catarina؛ Varum, Humberto (Islamic Azad University, South Tehran Branch, 2009-07-01)
    This article presents the seismic vulnerability assessment of the S. João de Loure bridge, inPortugal. The single span steel bridge has riveted joints, commonly affected by corrosion,which can lead to a significant ...

  • Analysis On Response Of Dynamic Systems To Pulse Sequences Excitation 

    Shuang, Li؛ Changhai, Zhai؛ Lili, Xie (Islamic Azad University, South Tehran Branch, 2009-07-01)
    Near-fault ground motions with long-period pulses can place severe demands on structures near an active fault. These pulse-type ground motions can be represented by pulse sequences with simple shapes. Half-sinusoidal pulse ...
