Perhaps the greatest advantage of reinforced concrete construction is continuity. SMCL/ML (Very hard clay)SM was utilized as the substructure soil layer. RC walls under seismic effects, general review. structures are durable if designed and laid properly. A thick concrete cover of low permeability is more likely to prevent chloride ions from an external source from reaching the steel and causing depassivation. Derechos 4). Advantages of Concrete Very durable Low maintenance Does not rust, rot, or burn Absorbs & retains heat (increases efficiency in buildings and cuts heating/cooling bills) Wind and water resistant Non-combustible (fire safe) Effective soundproofing material Disadvantages of Concrete More expensive Ekrami Kakhki, S., Kheyroddin, A. The advantages of FRP products over other materials include: Fibre Reinforced Polymer materials are designed to operate in aggressive environments. 10 and Table 5, by decreasing the groundwater level of the substructure soil from 0 (Full water) to 60m (dry), the sensitivity index decreases by 25%. Part of (2021). Box girder bridges are often subject to cracking due to wet temperature changes caused by the heat of hydration in the early stages; however, current studies do not provide an effective method for considering this effect. This is due to the effect of soil saturation conditions on the reduction of the resistance parameters, such as shear strength, shear modulus, friction angle and subsequently, the sudden subsidence of the soil. (2022). Tying is also a means of keeping laps or splices in place. (2009) evaluated a simplified model for damage in squat RC shear walls. (2016). Buildings with structural concrete frames are inherently quieter, stronger, safer, more energy efficient, and less expensive to maintain that buildings constructed with steel. The effect of the water table on the bearing capacity of a shallow foundation. It has the advantages of Other comparative reasons are listed below. Furthermore, the vulnerability of the frames with and without considering the SSI was compared with each other.

Disadvantages Span lengths are usually restricted to 40ft when normal reinforced concrete otherwise spans greater than that , can cause lateral deflections. The reinforcement layout and the dimensional specifications of columns, beams and RCSWs of the frames are shown in Table 2. Unit costs per tonne can vary enormously as there are a combination of factors that influence the overall cost. Seyed Ali Ekrami Kakhki is a Ph.D. student of Structural Engineering, Civil Engineering Department, Semnan Branch, Islamic Azad University, Semnan, Iran. Engineering Structures, 31, 22152223. High groundwater levels in the subsoil can reduce its bearing capacity and lead to the destruction of the foundation and damage to the structure. In some cases, single-family houses or simple low-rise residential buildings are constructed without any engineering assistance. Carbon fibre, of which there are 3 types (Type I, II, III) can be used separately or in conjunction with the glass fibre as a hybrid to increase the stiffness of a structural member or the area within a structure, so that the stiffness exceeds the value possible using only glass fibre. Considering the SSI makes the analysis a time-consuming process, but using it leads to more realistic results than conventional methods. https://doi.org/10.1016/j.soildyn.2012.08.008, Jiang, J., Zhang, Q., Li, L., Chen, W., Ye, J., & Li, G. Q. Seismic soil-structure interaction response of inelastic structures.

Inadequate cover is invariably associated with areas of high corrosion risk due to both carbonation and chloride ingress. B., Priestley, M. J. N., & Park, R. (1988). Afterward, a parametric study of the structures (foundation thickness) and substructures (soil types, soil densities, soil saturation conditions and soil layers) was performed. In this approach, the springs are incorporated to demonstrate the foundation and adjacent soil (Pitilakis & Clouteau, 2010). WebSeismic Retrofit of Existing Reinforced Concrete Buildings Understand the complexities and challenges of retrofitting building infrastructure Across the world, buildings are gradually becoming structurally unsound. In this essay, the progressive collapse resistance of the reinforced concrete wall-frame structures was evaluated with and without considering the soilstructure interaction. Performance of typical plan concrete buildings under progressive collapse. EN 199815:2004, Eurocode 8: Design of structures for earthquake resistance Part 15: Specific rules for concrete buildings. In the case of the environment with high damping, the lower limit is recommended, and in the environment with low damping, the higher limit is suggested. The characteristics of the studied substructure soils are represented in Table 6 (Qian et al., 2022). Alternate path analysis and design guidelines for progressive collapse resistance. The water in the pores of Portland Cement Concrete is normally alkaline with a pH in the range of 12.5 to 13.5. The steel bars accept tension and the concrete accepts pressure. has very good strength in tension as well as compression. https://doi.org/10.1016/j.istruc.2019.04.011, Scalvenzi, M., & Parisi, F. (2021). Composites offer the designer a combination of properties not available in traditional materials. https://doi.org/10.1007/s11709-016-0372-8, Farahani, A., Kheyroddin, A., & Sharbatdar, M. K. (2018). New guidelines and codes have been published to reduce the potential risk of progressive collapse of the structures, such as those provided by the U.S. Department of Defense (DoD, ) and the General Service Administration (GSA,).

As shown, the SI value of the RCSWs frame in FLAC software is less than the RCSWs frame in SeismoStruct software. Many were constructed before seismic load capacity was a mandatory component of building standards, and were often built with low-quality Bracing is one of the most essential and crucial parts of the structures that helps to improve the stability of the building and resist the buildings from earthquakes. FRPs are typically organized in a laminate structure, such that each lamina (or flat layer) contains an arrangement of unidirectional fibres or woven fibre fabrics embedded within a thin layer of light polymer matrix material. Indeed, M&E contractors quote an additional cost of horizontal services distribution below a profited slab of up to 15%. For this purpose, soil, foundation and RCSWs frames were simultaneously modeled in FLAC software with and without column removal (Fig. 1. A reinforced concrete section where the concrete resists the compression and steel resists the tension can be made into almost any shape and size for the construction industry. High-fidelity FE models for assessing progressive collapse robustness of RC ordinary moment frame (OMF) buildings. Therefore, RCSWs frames with a foundation thickness of 180cm have better conditions in preventing progressive collapse. The corrosion and deterioration mechanisms are essentially the same for both carbonation and chloride attack. Effect of near-fault and far-fault earthquakes on a historical masonry mosque through 3D dynamic soil-structure interaction. Research and practice on progressive collapse and robustness of building structures in the 21st century. SYY contours of the RCSWs frames following the column removal with various soil densities. The progressive collapse of the reinforced concrete (RC) structures can be caused by various types of abnormal loads, for example, gas explosions, bombs, fire, earthquakes, foundation failures, and construction or design errors (Mello et al., 2020; Petrone et al., 2016; Qian et al., 2021). Afterward, the effects of different parameters of the progressive collapse of the 20-story RCSWs frames, including soil layers, soil types, soil density, foundation thickness, and soil saturation conditions, were investigated. All this saves time. Because the steel components are made of alloy metal. The Braced frame is basically a structured system designed to withstand the High wind and the forces of the earthquakes.
