This study aims to undertake a statistical study to evaluate the accuracy of nine models that have been previously proposed for estimating the ultimate resistance of plate girders subjected to patch loading. For each model, mean errors and standard errors, as well as the probability of underestimating or overestimating patch load resistance, are estimated and the resultant values are compared o...

Synchrotron radiation facilities are very important in different areas of fundamental and applied science to investigate structures or processes at small scales. Magnet–girder assemblies play a key role for the performance such accelerator machines. High structural eigenfrequencies magnet–girder required assure sufficient particle beam stability. The objective present parametric study was numer...

Bridge structures are vital for majority of Sudanese due to the fact that they live besides rivers, valleys and inside islands. construction is faced by it extremely expensive. Cost such affected load which accordingly dictates required dead Loads from both superstructure substructure. In this analytical study a light bridge derived making use AASHTO principles. This practical data collected se...

We present a design of the girder to accommodate injection of 1133 MeV kinetic energy H− ions from the linac [1] into the LEB. This design is based on Colton and Thiessen’s design [2] for 600 MeV ions, and does not require a modification of the current [3] LEB lattice.

The main girders of the I-section steel-concrete composite twin girder bridge is usually connected together by frame cross bracing. When with welding, flat plates for stiffening can be used to strengthen connection ensure effective transfer forces between two. In this paper, finite element simulation method study influence plates. results show that, compared structure without stiffening, when s...

In this paper, the shear resistance and design of stainless steel plate girders at elevated temperatures are investigated. A broad range parameters influencing structural response in fire taken into account, considering (i) austenitic duplex grades, (ii) rigid non-rigid end posts, (iii) different aspect ratios for unstiffened portions girders, (iv) various web slendernesses (v) temperature leve...

The first step in the design of plate girder is to estimate the self-weight of it. Although empirical formulae for the same are available, the level of their accuracy (underestimate or overestimate) with respect to actual self-weight is not known. In this paper, optimized sections are obtained for different spans subjected to different live load carrying capacities and self-weights are estimate...

We describe the studies on dynamic aperture for the Swiss Light Source (SLS) 2.4 GeV storage ring including mini gap insertion devices, magnet misalignments and magnet multipole errors. We present a novel method for calculating the Touschek relevant effective lattice momentum acceptance and lifetime. Finally we describe the design of girders optimized for static and dynamic fatigue with high pr...
