Recycled aggregate concrete (RAC) has gradually received attention in recent years for sustainable development. However, the adaptation of RAC structural elements is becoming less popular due to lack proper design guidelines. Thus, encourage application RAC, it essential develop a framework predicting shear capacity beams. The data-driven prediction demonstrated excellent accuracy compared traditional empirical equations. This study proposed using machine learning. In this paper, 401 samples...
Despite 70 years of investigations in understanding the shear behaviour reinforced concrete members, it is again gaining attention among structural engineers as recently issued Australian design standard, AS 3600 updated its provisions and ACI 318 unveiled new one-way equation. This study investigates equations 318–19 3600–2018 highlighting their strengths weaknesses. A detailed parametric performed on a database 1237 tests point loaded RC slender beams without reinforcement. An Artificial...
Abstract Aggregate interlock is a stress transfer mechanism in cracked concrete. After concrete cracks under tensile loading, crack interfaces can experience significant slip deformation due to the applied kinematics. Upon rising along interfaces, aggregate stresses are generated which shear and normal stress. Many experimental programmes analytical expressions have been developed for several decades. However, finite element model considering realistic surfaces was still not developed. The...
Abstract Organic soils (i.e., muskeg, peat deposits) cover 18% of the Canadian landscape and many energy pipelines cross these soil terrains over large distances. Thermal changes due to operational environmental reasons pose a significant threat structural integrity safety pipeline systems in soils. Engineering design muskeg involves challenges, mainly lack understanding mechanical behavior organic Such knowledge gaps have caused an absence well-adapted soil-pipe interaction (SPI) assessment...
The Australian Concrete Code (AS 3600) went through a number of significant changes to the shear provisions in last decade introduction modified compression field theory. However, there were some discrepancies identified, specially related minimum reinforcement provisions. This paper investigates parameters which affect reserve strength using database tests beams with reinforcement. current concrete code 3600-2018), bridge design 5100-2017) and American institute (ACI 318-19) reviewed 1237...
For rural bridges in Australia, a common design practice is pouring in-situ concrete on top of beams order to tie all the together and distribute load. However, on-site creates more risk contractors prefer avoid it. Another method using transverse post tensioning beams. This article investigated behaviour post-tensioning bars providing load distribution between ultimately comment their effectiveness compared poured decks. Currently, industry has not completely this matter accurately....
Abstract A systematic research program was undertaken with the objective of developing quantitative geotechnical parameters to support soil-pipe interaction assessment for buried pipelines in muskeg. For this purpose, a field investigation comprising cone penetration testing (SCPT) shear wave velocity (Vs) measurements, electronic vane (eVST), full-flow ball (BPT), and pressuremeter (PMT), along fixed-piston tube soil sampling muskeg terrain. The data from were initially interpreted obtain...
Concrete is a heterogeneous and quasi-brittle material that can experience cracking even before reaching its ultimate limit state. Thus, the optimum utilization of this depends on how well effect minimized by safeguarding stress transfer after cracking. Stress in cracked concrete has been investigated since 1970s, yet existing codebased expressions for predicting shear were based limited experimental data leading to insufficient prediction capabilities. In recent years, machine learning (ML)...
