Characteristics of Horizontal and Vertical Near-Field Ground Motions and Investigation of Their Effects on the Dynamic Response of Bridges
Recently, concerning failure of structures due to earthquakes, special investigations of near fault ground motions have been noticed. Hence, in this paper, characteristics of near field ground motions have been considered in horizontal and vertical directions. In this consideration, the record averages have been compared with Uniform Building Code and Eurocode8 spectra in two levels. In additio...
متن کاملLarge-Amplitude Periodic Oscillations in Suspension Bridges: Some New Connections with Nonlinear Analysis
This paper surveys an area of nonlinear functional analysis and its applications. The main application is to the existence and multiplicity of periodic solutions of a possible mathematical models of nonlinearly supported bending beams, and their possible application to nonlinear behavior as observed in large-amplitude flexings in suspension bridges. A second area, periodic flexings in a floatin...
متن کاملBuilding Bridges through Scientific Conferences
Getting together to exchange ideas, forge collaborations, and disseminate knowledge is a long-standing tradition of scientific communities. How conferences are serving the community, what their current challenges are, and what is in store for the future of conferences are the topics covered in this Commentary.
متن کاملProbabilistic Evaluation of Seismic Performance of RC Bridges in Iran
Many existing bridges were designed without adequate consideration of seismic risk. The full or partial collapse of even one major bridge in a city or community would have destroying results. There has been focuses on developing fragility-based seismic vulnerability of existing usual bridges in Iran or support decision making on seismic upgrade. This article focuses on developing performance b...
متن کاملLecture 19: Constructive Reals and Infinitesimal Calculus
We will present a very interesting theorem from Bishop and Bridges, and then we will briefly consider the nature of nonstandard models of the classical reals as presented in H.J. Keisler’s book, Elementary Calculus and his free 203 page instructor’s book entitled Foundations of the Infinitesimal Calculus [8] which is provided as a course resource with this lecture. We have not covered the basic...
