It is now widely recognized that the masonry infill frame used in reinforced concrete structures (RC) greatly enhances both rigidity and strength of surrounding frame. The lateral loading behavior this RC different from without infill, although structural contribution walls discarded many countries, including Algeria. This paper aims to focus on effect openings changing distribution panels glob...

A novel CFS composite wall filled with cement-based lightweight polymer material (CFS-CLPM wall) has been proposed and proven to have excellent architectural mechanical performance. To promote its application in prefabricated concrete (PC) frame structures, two full-scale specimens were designed tested under cyclic loading investigate the failure mode, hysteretic response energy dissipation of ...

BACKGROUND While matrix-induced autologous chondrocyte implantation (MACI) has demonstrated encouraging outcomes in the treatment of knee chondral defects, there remains little available research specifically investigating its use in the patellofemoral joint. PURPOSE To prospectively evaluate the clinical and radiologic outcome of MACI in the patellofemoral joint. STUDY DESIGN Case series; ...

Conventional design of steel plate shear walls SPSWs assumes that 100% of the story shear is resisted by each infill panel. Following this approach, strength provided by the boundary frame moment resisting action, which provides the SPSW with overstrength, is neglected. While this design assumption has a positive impact on seismic performance of SPSWs, no analytical work has been done to quanti...

This study presents preliminary results of research on pre-Angkorian canals near the ancient settlement of Angkor Borei in the southern Mekong delta of southern Cambodia. The canals have been mapped by aerial photograph interpretation and investigated in the field by hand auger drilling of two canal traces and trenching of one of these. Luminescence profiling through the canal infill successful...

Concrete-filled fiber-reinforced polymer tubes (CFFTs) have attracted interest for their structural applications in corrosive environments. However, a weak interfacial strength between the fiber-reinforced polymer (FRP) tube and the concrete infill may develop due to concrete shrinkage and inadequate concrete compaction during concrete casting, which will destroy the confinement effect and ther...

To reduce maintenance costs, municipalities and schools are starting to replace natural grass fields with a new generation synthetic turf. Unlike Astro-Turf, which was first introduced in the 1960s, synthetic field turf provides more cushioning to athletes. Part of this cushioning comes from materials like crumb rubber infill, which is manufactured from recycled tires and may contain a variety ...
