The Barcelona model is one of the most widespread models used in the nonlinear finite element method for simulating the real behavior of concrete. The strong robustness of this model can be attributed to two main reasons, the first one being its ability to account for the elastic stiffness degradation induced by plastic straining and the second one the aptness of considering the stiffness recovery...
Spur-dikes are efficient hydraulic structures that are made for numerous purposes. They have one end on the stream bank and another extending into the current. As a result of the existing spur-dikes in the stream course, the local scour phenomena usually occur around them, leading to several predicaments which have been of great concern to the hydraulic engineers. For the present work, laboratory...
Exploring acceptance on benefits of solar farm implementation in Malaysia. Implementation of solar farms to generate electricity is still low in Malaysia, where only 1%, or 227.5 MW of the total installed electrical capacity in Malaysia was produced from solar PV installations in 2016. Renewable energies, e.g. solar energy, have been adopted in many countries to generate electricity as a response...
This study analyzes the effects of the incorporation of the granite powder (GP) as a partial replacement of the sand in the concrete in percentages of 10%, 15%, 20% and 30% to carry out a mix design of 210 kg·cm–2. Seeking to find an optimal proportion to increase its mechanical properties where the geotechnical characteristics of the aggregates were identified, workability, temperature, beams and...
Currently, in view of the previous theoretical and experimental researches, the regulatory documents for the calculation of reinforced concrete elements strengthened by composite materials and the calculation and design of fiber reinforced concrete structures are in force in Ukraine and in the world. Simultaneous strengthening of the compressed and tensile zones has not been sufficiently studied....
This research aimed to gain a better understanding of how the addition of fiber influences the punching shear capacity of two-way slabs by conducting an experiment into the structural behavior of flat slabs with and without a square opening using different volume fractions of hybrid steel-polypropylene fiber (0%, 0.9%, 1.05% and 1.8%). Ten 700 × 700 × 70 mm slabs were divided into five pairs, with...
