Soil layers are deposits that have formed over a long time. 9. It was found that by lowering the groundwater level from 0 (full water) to 60m (dry), the sensitivity index decreased by 25%, and the condition would be better to prevent the progressive collapse. Rather it should be just one of a number of issues that should be considered when making the choice of frame material. As shown in Fig. Cracking defects can allow moisture to penetrate and corrode the reinforcement. It requires high tensile steel, which is 2.5 to 3.5 times costlier than mild steel. In addition, it was determined that by changing the substructure soil type from type 4 (Clay-MC) to type 1 (Rock), the use of layer 1 (SM) and layer 2 (SM-CL/ML (Very hard clay)-SM), and the soils with high density, the condition of the structures is better to prevent progressive collapse. https://doi.org/10.1016/j.engstruct.2018.06.082, Article Furthermore, the results showed that the displacement of the stories increased with the increase in the foundation thickness. Thus, the density of the substructure soil can be increased by deliberate compaction. 12. Dynamic soil-structure interaction. Anchor is known as the product of force by distance. This can represent up to 4% of the frame cost. These structures are However, it can lose strength with heat or time, especially when not properly cured. Numerical investigation on progressive collapse resistance of post-tensioned precast concrete beam-column assemblies under a column-loss scenario. Increasing the relative density of the soil has many advantages, including improving soil properties, increasing soil resistance properties, bearing capacity of the soil, bearing capacity of surface and deep foundations, and reducing the inappropriate soil subsidence and risk of liquefaction. structures are durable if designed and laid properly. Progressive collapse resistance of RC frames under a side column removal scenario: The mechanism explained. The effect of soil density was investigated on the progressive collapse of RCSWs frames following the middle column removal. One of the most common uses for FRP involves the repair and rehabilitation of damaged or deteriorating structures. Other comparative reasons are listed below. The rise of the groundwater in the fine-grained soils causes the swelling of the soil grains and in the coarse-grained soils it causes the reduction of the internal friction angle of soil grains. Cement hydrates from microscopic opaque crystal lattices encapsulating and locking the aggregate into a rigid structure. Wolf, J. The minimum floor-to-floor height is almost always achieved with a concrete flat slab and separate services zone. Journal of Building Pathology and Rehabilitation, 6, 18. His research interests include the progressive collapse of concrete structures, tall buildings, and soilstructure interaction. SYY contours of the RCSWs frames with different soil densities following the middle column removal are represented in Fig. A light film of rust or mild film is not objectionable. After the foundation is built, it can be used for the Sulfates in the soil or in groundwater, in sufficient concentration, can react with the Portland cement in concrete causing the formation of expansive products which can lead to early failure of the structure. Loading in the frames was performed according to the DoD regulations, and the sensitivity index was obtained for each level of groundwater (Fig. Materials and Structures, 30, 139147. In this approach, the vulnerability of the foundation, superstructure, and soil in progressive collapse can be accurately investigated (Far & Flint, 2017). Unfortunately, in many cases there is not the necessary level of expertise in design and construction. Department of Defense (DoD). 17, by changing the soil layer from layer 1 (SM) to layer 6 (SMVery soft claySM), the sensitivity index increases by 53.7%. Reservados 1998 - 2009 Hard-Soft Service v2.0. The tensile and compressive stresses of the structural members change in proportion to the change in the size of the bending moment. On the other hand, removing a member with SI=1 causes the collapse of the whole structure or a part of it. https://doi.org/10.1061/(ASCE)EM.1943-7889.0001723. Robustness of reinforced concrete frames against blast-induced progressive collapse. The vulnerability of the frames against progressive collapse was investigated with the middle column removal scenario from the first story, based on the sensitivity index. The single inelastic force-based plastic-hinge frame elements (infrmFBPH) with 400 section fibres and 16.67% plastic hinge length were utilized for modeling the beams and columns. Resistant to weak acids and especially sulfates, this cement cures quickly and reaches very high durability and strength. 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. Confined concrete model under cyclic load. Unit costs per tonne can vary enormously as there are a combination of factors that influence the overall cost. Typical mechanisms leading to durability problems are as below: Steel reinforced concrete may be considered to have failed when significant cracks occur. At first, the initial failure should be localized, and should spread throughout the structure from one part to the other. In fact, the shear wall and flexural frame are each deformed in bending and shear modes, respectively. Prestressed concrete can be designed avoiding the tensile cracks in the concrete. sistema. The exit of water and air from the soil mass with compaction causes a decrease in porosity, an increase in specific weight, and as a result, an increase in the relative density of the soil. Loading was performed in the structures according to the DoD guidelines. The vulnerability of the frames to progressive collapse was determined based on the sensitivity index. In flexural wall-frames, the displacement and flexural anchors are less than RC frames. It has also good tensile strength. 103 was considered the threshold for the convergence criterion based on the assumed displacement/rotation. The numerical methods to study the effect of SSI can be classified as the direct approach and the substructure approach (Cavalieri et al., 2020; Li et al., 2014; Mourlas et al., 2020). According to these guidelines, there are several approaches to evaluate the progressive collapse of the structures, such as linear dynamic, linear static, nonlinear dynamic and nonlinear static approaches (Marjanishvili, 2004). Weba) High tensile strength - one of the strongest of all commercial reinforcing fibers when it comes to tension, carbon fiber is very difficult to stretch or bend. R.C.C. Ekrami Kakhki, S., Kheyroddin, A. Structural failure can occur in FRP materials when tensile forces stretch the matrix more than the fibers, causing the material to shear at the interface between matrix and fibers, tensile forces near the end of the fibers exceed the tolerances of the matrix, separating the fibers from the matrix and tensile forces can also exceed the tolerances of the fibers causing the fibers themselves to fracture leading to material failure. That said: Design delays can impact production and your schedule, especially when a new product or method is in play. It was also mistakenly believed that it would prevent freezing. When the cement paste within the concrete hardens this conforms to the surface details of the steel, permitting any stress to be transmitted efficiently between the different materials. Engineering Structures, 251, 113470. https://doi.org/10.1016/j.engstruct.2021.113470, Qian, K., Lan, D. Q., Li, S. K., & Fu, F. (2021). Furthermore, from a practical point of view, 3D modeling of soil, foundation and structure in the laboratory in real dimensions is very difficult, and scaling the soil may lead to the different results than the real model. Then the whole section will be in compression and there are no tensile caracks. This button displays the currently selected search type. Structures, 33, 25342545. Journal of Engineering Mechanics, 146, 111. The model nodes were all restrained against the out-of-plane displacements, the frame's vertical axis, and rotation around the in-plane horizontal axis. Timber has higher structural efficiency as carried load per unit weight compared to reinforced concrete and steel structures. In the flexural wall-frames, the shear in supports is more uniform and economical, and they have more ductility, indeterminacy and safety than RC frames (Stafford Smith & Coull, 1991). Provided by the Springer Nature SharedIt content-sharing initiative. 10). The displacement rate was determined to be at least 0.1mm per step. Ali Kheyroddin is a Distinguished Professor, Department of Civil Engineering, Semnan University, Semnan, Iran. Concrete construction, does, however, require a certain level of technology, expertise, and workmanship, particularly in the field during construction. WebSeismic Retrofit of Existing Reinforced Concrete Buildings Understand the complexities and challenges of retrofitting building infrastructure Across the world, buildings are gradually (2016) was utilized as a reference. Consequently, the dry condition of the substructure soil is ideal for preventing progressive collapse. https://doi.org/10.22059/CEIJ.2019.247588.1449, Kiakojouri, F., De Biagi, V., Chiaia, B., & Sheidaii, M. R. (2020). In order to intensify and reinforce the tensile strength of concrete, steel is utilized. Developments in the modern reinforced concrete design and construction practice were pioneered by European engineers in the late 19th century. Design applications ranges from single-family buildings in countries like Colombia to high rises in China. Glass reinforced polymers are strongest and most resistive to deforming forces when the polymers fibers are parallel to the force being exerted, and are weakest when the fibers are perpendicular. Engineering Failure Analysis, 136, 106228. https://doi.org/10.1016/j.engfailanal.2022.106228, Esmaeilnia Omran, M., & Hoseini Karani, A. Loading was done in the RCSWs frames according to the DoD guidelines. This mechanism can be seen by comparing the SYY contours of the RCSWs frames in the saturate states (0, 13, 20, 30, and 40m) with the dry state (60m). It was found that by changing the substructure soil layer from layer 1 to layer 6, the sensitivity index increased by 53.7%. (2013). These advantages are; are classified under the headings of quality, cost, time, safety, cleanliness, regularity, and ecology. Assessing seismic behavior of a masonry historic building considering soil-foundation-structure interaction (Case study of Arge-Tabriz). So, only use fresh raw water or portable water for mixing concrete. Modeling of the 20-story RCSWs frames with various soil layers in FLAC software, Plot of sensitivity index versus soil layers. 5. Bao and Kunnath (2010) investigated the progressive collapse of RC wall-frame structures following the sudden damage of a significant part of the shear wall.
