Automatic hydraulic press is widely used for pressing ceramic wall and floor tiles, the four columns of its frame withstand the all work force when it works, so the columns are the key compartments of the frame, and its work performance has an important impact on the structural performance of the entire automatic hydraulic press. Took the column thread connection of 32.8MN automatic hydraulic p...

Fires can cause substantial damage to structures, both non-structural and structural, with economic losses of almost 1% GDP in developed countries. Whilst design codes allow engineers to design for the primary design driver, property protection is rarely, if ever, designed for. Quantification and design around property protection has been used for some time in the seismic community, particularl...

Abstract Over the last few decades aluminium alloys have been increasingly used in construction sector due to their favourable properties. Thereafter, many research projects carried out with aim obtain a more comprehensive understanding of structural performance and develop accurate reliable design formulae. The scope this paper is provide review by discussing reported experimental, numerical a...

fiber reinforced polymers (frp) have widely used for the purposes of enhances strength and ductility of concrete columns. proper design of such hybrid columns, however, requires a better recognition of the behavior of concrete columns confined with frp. in this paper, the influence of frp thickness, concrete compressive strength, and column size on the performance of eccentrically loaded reacti...

The ability to perform accurate nonlinear simulations is a key component in the assessment of the behavior of seismic force resisting systems. A three-dimensional distributed plasticity formulation for composite beam-columns suitable for nonlinear static and dynamic analyses of composite seismic force resisting systems has been developed. New uniaxial constitutive relations are developed for th...

INTRODUCTION The total hip arthroplasty (THA) as part of acute fracture management is used for acetabular fractures in elderly patients. Our objective was to assess the stability of osteosynthesis performed using 2 different techniques in combination with THA in an experimental model. MATERIALS AND METHODS We conducted 20 experiments using the left-side hemipelves composite bone models. There...

Composite columns are often used in constructing high-rise structures because they can reduce the size of a building's while increasing usable area floor plan. This research aimed to develop nonlinear 3D finite element analysis model using ABAQUS, version 6.13-4, various round composite column designs with varied multi-skin tubes for solid and hollow subjected eccentricity loads (90, 180 mm). E...

Sequences and arrays with good auto and cross-correlation are useful in communications and digital , .. 'atermarking respectively. Two-valued autocorrelation is relatively easy to achieve. However, sets of pSfudonoise sequences with good cross-correlation arc small and difficult to find. Here, the cross-correlation for particular shifts of m-sequences and GM\V sequences is analysed by looking a...

One of the reasons that cause collapse buildings is deficient short columns, which need to be retrofitted prevent building in a potential earthquake. External reinforced concrete (RC), steel plates, and fiber-reinforced polymer (FRP) jacketing are standard retrofitting methods retrofit columns increase their shear capacity. However, compression failure, effectiveness FRP quite limited due prema...
