Building information modeling (BIM) has proven to be a valuable technology in the fields of architecture, construction management, and maintenance management. However, its full implementation in structural engineering remains unfulfilled due to the persistent use of outdated design methods. Insufficient automation in the design process could lead to structural defects,...Read More

Building information modelling (BIM) is an appreciated technology in the field of architecture and construction management. Collaboration of information in BIM has not been fully utilized in the structural engineering stream as many engineers keep on working with previous prevailing design approaches. Failure to adequately facilitate automation in design could...Read More

Over the last decade, the educational sector worldwide has been steadily embracing the digital technology revolution by integrating industry 4.0 and web 3.0/4.0/5.0 concepts. Many higher education institutions are leveraging this opportunity offered by the advancements in digital technology and are strongly investing in e-Learning systems offering flexible and blended...Read More

This paper presents an experimental study on the dynamic tensile performance of high-strength concrete reinforced with fibers of different types and contents. In total, five different high-strength concretes with a similar compressive strength of 85 MPa were investigated. One of the five concrete was a plain high-strength concrete (HSC) as...Read More

This paper presents an experimental study on the effect of high strain rate on the tensile behavior of two Strain-Hardening Cement Composites (SHCCs), compared to that of Fiber-Reinforced High-Strength Concretes (FRHSCs) with similar compressive strength. One of the SHCCs was reinforced with 2% of polyvinyl alcohol (PVA) fibers by volume...Read More

High velocity projectile impact (HVPI) test was carried out on three classes of cement composites to assess their performance. The tests were conducted on thick block specimens using non-deformable ogive-nosed projectiles with a mass of 250 g and a diameter of 28 mm at approximately 400 m/s. The severity of damage was quantified by the depth of penetration...Read More

This study investigates the influence of several material properties underlying the failure mechanism of high-strength concrete (HSC) under uniaxial compression. An experimental-numerical characterization of a single inclusion block (SIB) – an idealized composite comprising of a granite cylindrical core embedded within a high-strength mortar (HSM) matrix – is first carried out.  Parametric...Read More

This paper presents an experimental study on the effect of high strain rate on the compressive behavior of two strain-hardening cement based composites (SHCCs), compared to that of fiber-reinforced high-strength concretes (FRHSCs) with similar compressive strengths. One of the SHCCs was reinforced with 2% of polyvinyl alcohol (PVA) fibers by...Read More

An experimental research was conducted with the objectives to study the effects silanes (amino, vinyl, and epoxy-based) and their derivatives (silane oligomers and silane nanoparticles) on cement hydration and mechanical properties of mortars. Silanes and silane derivatives are used as coupling agents to combine different compositions in mortars and to...Read More

This paper presents experimental and numerical studies on the performance of seven high-performance fiber-reinforced cement-based composites against high velocity projectile impact (HVPI). The materials investigated involved four fiber-reinforced high-strength concretes (FRHSCs) with 28-day compressive strengths ranging from about 60 to 140 MPa, two strain hardening cement-based composites (SHCCs), and a fiber-reinforced high-strength mortar...Read More

This paper presents an experimental study on effect of high strain rate on compressive behavior of plain and fiber-reinforced high-strength concrete (FRHSC) with strength between 80 and 90 MPa. A Split Hopkinson pressure bar equipment was used to determine the concrete behavior at strain rates from 40 to 300 s−1. Fracture patterns...Read More

This paper presents a laboratory experimental study on the effect of high strain rate on compressive behavior of plain and fiber-reinforce high-strength concrete (FRHSC) with similar strength of 80-90 MPa. Steel fibers, polyethylene fibers, and a combination of these were used in the FRHSC. A split Hopkinson pressure bar equipment...Read More

This paper presents a laboratory experimental study on the effect of tensile strength and toughness on the resistance of cement-based materials to high-velocity projectile impact. Three types of cement-based materials with similar compressive strength but different tensile strengths and toughnesses were examined in terms of the penetration depth, crater diameter,...Read More

This paper presents an experimental study on effect of specimen size on the static strength and dynamic increase factor (DIF) of plain and fiber reinforced high-strength concrete determined from Split Hopkinson pressure bar (SHPB) tests. Four types of specimens were used to determine the static strength of the concrete including...Read More
