Numerical Modeling of Composite Systems: Composite CFT Connections and Composite Beams
The use of concrete-filled tubular composite members and composite beams has been implemented in many structural systems due to their robust structural performance, constructability, and inherent synergy when the steel and concrete components are properly designed and detailed together. While …

Postbuckling Analysis of Delaminated Composite Plates Under Compression (Composite Laminates)
Failure mechanics of delamination problems in composite laminates under compression is investigated. The failure modes in general may include prebuckling, postbuckling, delamination growth and final failure. Buckling load is determined by solving an eigenvalue problem using a subspace iteration …

Thermoplastic composite consolidation
Fabrication of high-quality composites from thennoplastic prepregs requires careful selection of the processing cycles so that intimate contact at the ply interfaces is achieved resulting in the formation of strong interply bonds and the process-induced residual stress is minimized to ensure …

Ultimate strength analysis of partially composite and fully composite open-web steel joists
The behavior of composite steel joists with various degrees of shear connection is investigated. The results of eight full-size composite joist tests, conducted as a portion of the study, are presented. Joist spans range from 24 ft. to 30 ft. and depths from 8 in. to 18 in. Six types of mechanical …

Investigation of composite façade mullions
… on the behaviour of this type of thermal break composite façade mullions under quasi-static loadings. Literature survey was carried out. Past research works on of the thermal break façade mullions was studied, as well as the current European standard specifying the performance requirement, proof …

Composite Multi resolution Analysis Wavelets
Composite dilation wavelets are a class of wavelets that include additional dilations from a countable subgroup of the invertible matrices. We consider the case when these additional dilation matrices form a finite group. A theory of MRA wavelets is established in this setting along with a theory …

Reinforced composite masonry shear walls
<p>The results of tests of reinforced composite masonry panels subjected to gravity and in-plane shear loads are discussed herein. Eleven walls were tested. Each of the walls was made from two wythes of brick-to-brick or brick-to-block, with a nominal 2-inch collar joint. In the first 10 walls, the …
