This manuscript delineates an extensive inquiry into a structure in Ankara, Turkey, specifically focusing on its existing state, retrofitting initiative, and concomitant software development. The evaluation of the building’s current state, earthquake loads, and anticipated structural stresses was conducted per the Turkish Seismic Code of 2018. The structural model was analysed, incorporating data derived from on-site inspections, surveys, and samples from the building’s concrete core and reinforcement elements by employing non-linear calculation methods. Remedial measures were undertaken after recognising deficiencies in the structure’s performance, including strengthening columns and selecting slabs by applying Fibre-Reinforced Polymer (FRP) composites. Subsequently, the authors engineered the FRP Composite Column Strengthening software. This software facilitates the computation of axial compression strength, shear strength, and ductility enhancements for columns after the retrofitting process.

In this investigation, the effects of different fabrics with 0.20% carbon fiber textile (CFT), 0.21% glass fiber textile (GFT), and 0.25% basalt fiber textile (BFT) on the properties of TR-UHPC were investigated by axial tensile tests. A bending test of the BFT-UHPC pavement slab was carried out. In terms of axial tensile performance, the fiber textiles ranked in the following sequence: CFT, BFT, and GFT. Additionally, the corresponding increases in the initial cracking strength and ultimate tensile strength were 18.0% and 21.9% for the CFT, 12.0% and 16.0% for the BFT, and only 9.1% and 8.0% for the GFT, respectively. Increasing the textile reinforcement ratio of the BFT from 0.25% to 0.50% improved the cracking stress and peak stress of the specimen by 12.0% and 15.9%, respectively. Moreover, the ultimate strain of the 0.50%-BFT reinforcing case was 1.4 times that of the 0.25%-BFT reinforcing case and 2.6 times that of the unreinforced specimen in terms of ductility. The results of the stacking test on the BFT reinforced UHPC pedestrian slab indicate that the mid-span deflection of the test slab under normal use load is 0.775 mm, which is only 19.8% of the deflection limit. Additionally, the test slab remained in the elastic stage without any cracking. The BFT effectively enhanced the toughness of the UHPC thin slab after cracking. It is expected to be applied as a novel structure to bridge pedestrian slabs, bridge decks, and other thin UHPC members, thereby improving the durability and mechanical properties of bridge structures.

“…In building, this material is frequently utilized because of its cheapness and flexibility to be molded into various sizes and shapes. The material's strength can withstand significant compression stresses as well [1]. Due to its brittleness, this material cannot be used as a stand-alone component in the building.…”

Structures made of reinforced concrete are susceptible to developing cracks when they are in the path of earthquakes, strong winds, or increased structural loading. It is therefore possible that it will be necessary to manage structural cracking in the Service Limit State to maximise the lifetime and strength of the structural components under any stress. Helical containment is superior to rectangular containment in terms of its ability to strengthen and ductile the Reinforced Concrete (RC) structural member. In the current work, six distinct beams were each subjected to a series of tests to see how they behaved in terms of cracking when subjected to bending loads. Each of these tests used a unique helical pitch space distance. The beams all measured 150 mm by 150 mm and 750 mm in length. They were designed in accordance with the criteria of Euro code 2, with the identical dimensions. Both 50 and 100 mm were used to take the measurement for the helical pitch. The findings indicate that the utilisation of helical elements does influence the cracking behaviour of the beams. The most important finding was that the measurement of the crack’s thickness was slightly reduced when the beams were restricted to a helical zone with a closer spacing between them. The fact that the theoretical crack is longer than the actual crack that was measured experimentally demonstrates that the Euro code 2 standard provides a more accurate forecast as well as a higher factor of safety. This is demonstrated by the fact that the theoretical crack is larger than the actual crack that was measured.
