Abstract: According to the law of rigid body motion, a body initially acted upon by a set of forces in equilibrium will experience no additional straining when subjected to a rigid body motion, and will remain in equilibrium after ...

Abstract: This paper presents design charts constructed from the softened truss model to facilitate the torsional design of reinforced concrete rectangular members. These design charts comprise a normalized failure mode diagram and ...

Abstract: The stability of a viscoelastic beam subjected to an axial compression resting on a viscoelastic medium is studied using a dynamic method. The governing differential equation of the problem is derived from the condition ...

Abstract: Geometric nonlinear analysis of structures is not a simple extension from its counterpart of linear analysis. In this article, some research works conducted primarily in the past two decades ...

Abstract: It has been shown in previous research that, relative to (the usually considered case of) a single impact, multiple impacts (clattering) of rigid casings can greatly enhance the probability of ...

Abstract: The quasi-plastic-hinge approach proposed by Attalla et al. in 1994 for material nonlinear analysis is formulated using the total form expressions, which is generally computationally inefficient as numerical integrations ...

Abstract: A strut-and-tie design methodology is presented for three-dimensional reinforced concrete structures. The unknown strut-and-tie model is realized through the machinery of a refined evolutionary structural optimization ...
