The performance of asphalt pavement is highly affected by climate factors, such as temperature and precipitation. Different moisture conditions change the paving material properties, which consequently influence performance. Considerable research has been conducted to study effect factors on performance; however, there are no focused studies that have investigated pavements in cold regions. In this research, different design regions utilising data extracted from Long-Term Pavement...

This article presents experimental data and nonlinear finite element analysis (NLFEA) modeling for an innovative buckling restrained bracing (BRB) system. The were collected from qualification testing of introduced BRBs per the AISC 341 test provision modeling. BRB is made three parts: core bar, restraining unit, end units, in which duplicates different bar cross sections (i.e., fully threaded, threaded notched, smooth shaved) tested. this research come with parts, so-called fingers. These...

This research paper is part of an ongoing on the behaviour Reinforced Concrete (RC) beams retrofitted with Externally Bonded Carbon Fiber Polymer (EB-CFRP). A total 5 large-scale rectangular beams, previously damaged due to shear loading, were repaired and strengthened EB-CFRP tested in this study. The major cracks injected epoxy wrapped 2 layers discrete strips 100mm width 150mm center spacing. instrumented failure under three points loading simply supported configuration. measured test...

The current guidelines, namely ACI 440.2R and fib TG-9.3, quantify the nominal shear strength of strengthened reinforced concrete (RC) beams by simply summing up contribution three components: (Vc), steel stirrups (Vs), externally bonded fiber polymer (EB-FRP) (Vf). However, as reported in literature, this assumption is inaccurate due to an adverse interaction between EB-FRP stirrups. This research study adopts a machine learning method called Artificial Neural Network (ANN) model...

Unlike straight web I-girders, the construction industry’s demand for corrugated steel girders is increasing due to their high shear strength without needing transverse stiffeners. Although corrugation fabrication cost could be high, savings on material, transportation, and erection costs can compensate expenditures needed build flat-plated with This study investigates behavior of webs different geometries profiles (triangular trapezoidal) through laboratory testing. Following a detailed...

This research paper reports results of strength development properties ambient-cured alkali activated binders (AABs) and their reliance on different parameters, such as type pre-cursor materials & proportions, ratio activators, curing age. In this study sodium silicate (SS) hydroxide (SH) solutions were used to activate a blend low-calcium (class F) fly ash (FA) ground granulated blast furnace slag (GGBFS). A total 25 AABs mixes with various mix proportions are investigated in study. The...

The aim of this paper is to examine the effects using Ground Granulated Blast Furnace Slag (GGBFS) as a complete replacement Ordinary Portland Cement (OPC) in Reinforced Concrete (RC) beams. proposed GGBFS mix had an air content 1.4%, unit weight 2480 kg/m3, slump 201 mm, and compressive strength 30 MPa after 56 days curing. In addition, GGBFS-based sample have shown increased durability it passed less chloride ions when compared conventional concrete. A total four beams were cast then...

Abstract Given the high environmental impact of OPC concrete on CO 2 emissions, construction industry is moving towards low carbon alternate binders. In recent years geo-polymer (GPC) has come to forefront such efforts. However, challenges remain for GPC be considered as a main-stream material. Since relatively new material in industry, many its mechanical properties are still not fully understood. The current work looks at strength ambient cured GPC. This research paper part an ongoing...

Abstract This research study is conducted to investigate the flexural behaviour of steel fiber reinforced concrete (SFRC) prisms incorporating different types and volume fractions fibers, various grades concrete, specimen depths, all tested under displacement control mode using four-point loading configuration. Two fibers (hooked end straight) were incorporated into mixes at two dosages (1% 2%). Concrete with compressive strengths 40, 50, 70 MPa used cast samples. Specimen depth was also...

<abstract> <p>Industrial applications of fibre-reinforced concrete (FRC) in structures require extensive experimental and analytical investigations the FRC material properties. For design purposes involving flexural loading member, it is essential to have a predictive model for strength material. In present paper, fracture mechanics approach based on Bridged Crack Model (BCM) used predict steel (SFRC) beams. The assumes quadratic tension-softening relationship (σ-δ) governing...

Abstract This paper presents the results of an experimental investigation on shear capacity reinforced concrete beams. The beams under consideration are with glass fiber-reinforced polymer (GFRP) bars. Also, effect strengthening such is studied. For this purpose a total four were tested where two served as control beams, while other strengthened using U shape carbon (CFRP) sheets, bonded externally. Each beam 2.4 m long, simply supported and subjected to four-point load displacement mode....
