Abstract: A rheological stochastic model to predict the cyclic stress‐strain behavior of concrete subjected to uniaxial compressive loading is proposed. The model consists of rheological elements with random state variables with ...

Abstract: A new viscoelastic‐type connection isolator (damper), made of elastomeric material, is presented in this paper. Based on experimental results, a Kelvin‐Voigt‐type model was developed to simulate the behavior of the connection. ...

Abstract: This paper presents closed-form periodic solutions, accompanying stability analyses, and an analytically generated response spectra for a passive isolation system subjected to a harmonic base motion. This isolation system, ...

Abstract: A new, passive, dissipation element that utilizes Coulomb friction between slipping elements to brake horizontal building motions has been recently introduced. In concept, the device is composed of a large number of staggered ...

Abstract: The concept of the envelope curve which was based primarily on plain concrete is extended to confined concrete subjected to cyclic loading. Spirally confined normal weight and light weight concrete specimens were subjected ...

Abstract: For decades intrepid environmentalists have been building homes and other structures with a material that recycles wastepaper into an alternative construction material made with cement and other ingredients. They have ...
