This Study represents compatibility on Cold formed steel in I-Section beams and C-section with variable length parameters was 1000mm, 1500mm, 2000 mm under simply supported end condition subjected to uniformly distributed loading. The is of shell type Numerical simulation carried out using the Software ABAQUS. For validation series studies have been numerical model different parameters, such as...

Perforated cold-formed steel (PCFS) beams are increasingly used in constructional industry and become popular due to their advantages economic benefit. Apart from the light weight, openings PCFS can also be for services such as pipe utilities release more building space. However, with web perforations may collapse result of web-distortional buckling or flange/web distortional weakness caused by...

The paper presents the test results of beams made of chipboards, fibreboards, wood as per referenced items [1], [2], [3]. Adopting various rheological models, their behaviour in time under permanent load was described. The model testing of a box-section beam, with wooden flanges connected with continuous chipboard lacings, was described. It was found that the construction of beams made of unlim...

Abstract--L-shaped beams subjected to pure elastic-plastic bending are investigated thoroughly. The shifting and rotating of the neutral axis of the beam during bending and springback after unloading are described mathematically, while the curvatures of the beam before and after springback are given. The method proposed in this paper is valuable both to the further theoretical studies of the as...

We demonstrate the ability to determine the three-dimensional orientation of single molecules using cylindrical laser beams. Theory for fields with both radial and azimuthal polarizations is described in Section 2. Fluorescence image of the molecules is obtained from experiment and is presented in Section 3. Combining the theoretical and experimental data, we successfully determined the orienta...

moment-resisting frames have extensive usage in earthquake-prone areas and high ability in energy dissipation.after the earthquake in northridge 1994,kobe 1995 fixed connections of steel structures have shown poor performance and generally they were caught brittle fracture of beam flange weld to the column.in order to remedy to avoid similar situations in future earthquakes,researchers introduc...

In order to investigate the main influencing factors and development rules of shear performance high strength concrete (HSC) beams without web reinforcement under concentrated loads, analyze compare rationality China American Code formulas Zsutty formula, in this paper, 303 sets experimental data about test HSC at home abroad were selected, based on these data, calculation method capacity was d...
