The effects of Northridge (1994) and Kobe (1995) earthquake, intensive analysis testing efforts are currently being sought for higher ways designing seismic resistant steel connections. A connection with RBS (Reduced beam Section) is an acceptable solution to emphasizing a moment can be the most reliable type connection. Considering benefits lack information on resources in Indian standards, an...

The method of complex geometrical optics (CGO) is presented, which describes Gaussian beam (GB) diffraction and self-focusing along a curvilinear trajectory in inhomogeneous and nonlinear saturable media. CGO method reduces the problem of Gaussian beam propagation in inhomogeneous and nonlinear media to solving ordinary differential equations for the complex curvature of the wave front and for ...

In this paper, a displacement-based, variationally consistent, two variable refined theory for shear deformable beams is presented. The beam is assumed to be of linearly elastic, homogeneous, isotropic material and has a uniform rectangular cross-section. In this theory, the beam axial displacement and beam transverse displacement consist of bending components and shearing components. The assum...

Reduced web section beams in shear-yielding moment-resistant steel frames are used for energy dissipating of earthquakes. The finite element analysis indicates that failure mode of these beams are governed by the combination of shear force and flexural moment. Therefore the analysis of frames with reduced web section beams needs consideration of shear-flexural interaction in those sections. In ...

I present a derivation of the many qualitative changes to basic scattering theory that result when a ~partially! coherent matter beam inelastically interacts with a quantum target. The weak beam limit, where only one object in the beam interacts with the quantum target, is developed. Some of the basic changes to scattering theory are as follows. ~1! The transition probability can increase as th...

This study focuses on the behavior of a three-dimensional reinforced concrete dapped-end beam subjected to effects impact velocity and cross-section geometry by numerical simulation using ABAQUS (V6.14) software under constant load. The finite element is utilized simulate analyze drop obtain accurate detailed results. A sudden short-duration dynamic load that could involve very large deformatio...

The use of perforated (in particular cellular and castellated) beams has become widespread as their manufacturing processes keep minimising wasted material cost-effective by reducing self-weight steel structures, while allowing for larger clear spans. Although behaviour to time-invariant vertical loads been extensively investigated validated in laboratory setups, response reversible actions not...

We are developing an acceptance measurement system to evaluate the matching of the emittance of an injection beam to the acceptance of the AVF cyclotron. The system is composed of a phase-space collimator in the low energy section and beam intensity monitors which are installed just after the phase space collimator and in the high energy section. The phase-space collimator, which consists of tw...
