Precast concrete structure is a low-carbon building system that has been attracting extensive attention in recent decades. Beam–column joints are the weak links precast structures. Past studies showed five-spiral stirrups had excellent confinement effects and potential to enhance seismic performance of This study proposed reinforcement beam–column by using investigated their performance. Consid...

In this present study, experimental work was conducted to study the effectiveness of newly innovated steel-CFRP composite (CFRP laminates sandwiched between two steel strips) as stirrups. A total numbers of eight concrete beams were tested under four point loads. Each beam measured 1600 mm long, 160mm width and 240 mm depth. The beams were reinforced with different shear reinforcements; one wit...

Aiming to investigate the mechanical performance of UHPC T-section beams, five specimens are fabricated and tested, considering variable steel fiber volume fraction (SFVF). The code Association Francaise de Génie Civil (AFGC) is evaluated by test data. Additionally, based on Abaqus (2020), refined finite element analysis (FEA) models established validated experimental Moreover, parametric sensi...

Objectives This pilot study describes the physiological attributes of jockeys and track-work riders in Tasmania and investigates whether these attributes are associated with falls. Methods All jockeys and track-work riders licensed in Tasmania were invited to participate. The study group consisted of eight jockeys (two female, six male) and 20 track-work riders (14 female, six male). Measures ...

Transcription factor (TF) IIIB, the central transcription initiation factor of RNA polymerase III (pol III), is composed of three subunits, Bdp1, Brf1 and TATA-binding protein (TBP), all essential for normal function in vivo and in vitro. Brf1 is a modular protein: Its N-proximal half is related to TFIIB and binds similarly to the C-terminal stirrup of TBP; its C-proximal one-third provides mos...

This study presents the modeling of pull-out behavior deformed bars embedded inside reinforced concrete element. The simulation uses an in-house finite element package called 3D-NLFEA. Sufficiently small solid elements that consider frictional resistance and mechanical interlocking between bar thread matrix were used in simulation. effect compressive strength, cover thickness, stirrup configura...

Precast segmental reinforced concrete (RC) piers have been widely used in the construction of offshore bridges to speed up construction. Offshore cold regions are inevitably affected by seawater freeze–thaw cycles under periodic movement tides, which could reduce mechanical property RC piers. Based on low cyclic loading test 12 specimens with different cycles, axial compression ratio, diameters...
