Cyclic tensile testing of a three‐way panel connection for precast wall‐slab‐wall structures (2019)

Wall‐slab‐wall buildings, in precast configuration or not, are relatively widespread in many European and non‐European countries, independently of the level and nature of seismic hazard to which the country is prone. Thus, this building archetype, featuring no columns or beams, but only slabs and walls, can be equally found both in areas characterized by potentially high‐damaging tectonic earthquakes and regions where small‐to‐medium‐size natural/anthropogenic seismic events would instead be exp

Steel fiber reinforced concrete tensile testing with eliminated lateral wall effect (2022)

AbstractA test rig and a novel experimental procedure are introduced and qualified to obtain realistic tensile strength of steel fiber reinforced concrete specimen with supercritical fiber contents from direct tensile tests. To eliminate the wall effect an optimal shape is found employing the method of tension triangles that ensures uniformly distributed stresses throughout. By water jet cutting an initially rectangular casted specimen is tapered at the center. The resulting bone‐shaped specimen

Effect of Epoxide Content on the Vulcanizate Structure of Silica-Filled Epoxidized Natural Rubber (ENR) Compounds (2021)

The demand for truck–bus radial (TBR) tires with enhanced fuel efficiency has grown in recent years. Many studies have investigated silica-filled natural rubber (NR) compounds to address these needs. However, silica-filled compounds offer inferior abrasion resistance compared to carbon black-filled compounds. Further, the use of NR as a base rubber can hinder silanization and coupling reactions due to interference by proteins and lipids. Improved silica dispersion be achieved without the use of

Influence of Sulfur Ratio to Accelerator on the Crosslink Density, Mechanical, Dynamic, and Damping Properties of Unfilled Natural Rubber Vulcanizate (2022)

Natural rubber (NR) is a biopolymer with low vibration damping capacity. NR requires modification of its viscoelastic properties through crosslink in NR vulcanizates molecular chains as vibration damping. This study is the first to report a correlation between crosslink density and dynamic shear properties of NR vulcanizates, including hysteresis loop area, shear stiffness, equivalent damping ratio, and effective shear modulus. This correlation is necessary to develop NR vulcanizates properties
