Buckling and post-buckling behavior of various dented cylindrical shells using CFRP strips subjected to uniform external pressure: Comparison of theoretical and experimental data

Concrete is widely used structural material, all over the world. The excellent versatility, availability, and economy of the concrete makes it a pioneer of the construction industry when it is compared to other materials. Beams/columns are one of the main structural elements of building to respond to the effects, such as bending moment, shear, and torsion. Thus, it is important to investigate the relevant behaviors of members [1,2]. Steel fibers have been used to improve the characteristic properties of concrete in practice for many years. Besides the commercial use of fibers in concrete technology began in 1970s, particularly in Europe, Japan, and USA. In the structural application, concrete behaves as a brittle material with low tensile strain capacity and with some softening postpeak behavior in compression essentially due to the transverse strain capacity. The use of steel fibers in the

“…The hydraulic jack was used here to assess the static load of the test models. The maximum load of the setup was 900 kN, which was employed with a maximum stroke of 300 mm, and a constant speed of 0.016 mm/s, up to the collapse of the specimens [16][17][18][19][20][21][22][23][24][25][26][27]. Two linear variable displacement transducers with a maximum displacement of 100-300 mm (locations of LVDTs are shown as DT in Figure 5) were used.…”

The modern basic civil engineering concept is to design simplistic structures, by using innovative brand new manufacturing and assemblage concepts. As a result of this concept, arch type steel plates are used like the corrugated coatings. The main purpose of this work is to describe the Roll Form Machine (RFM) technology as used for the structures, especially for the roofs. Cold formed arch type steel structures may be fast and simple. These types of structures were used for temporary buildings in the US Army. Nowadays, this technology becomes popular and gets in consideration for civil life. However, the design concept of this technology does not have a theoretical model, and the calculations are evaluated according to the United States Standards. The uniaxial compressive behaviors of corrugated arch type steel members are observed, experimentally within this work.

“…The reason for these six bolts is the installation of a top plate assembly, which prevented these bolts from entering the axial load into the cylinder when it was tested with the crane. 37 After the test, the machine was manufactured, and laboratory samples were built. The galvanized steel plate (ST-52) is used for this research.…”

Thin-walled shell structures are characterized by a lightweight structural form with high strength. This structure has many applications in various engineering fields and is considered to be a basic tool in the modern industry. This study investigates the effect of CFRP on tanks after post-fire in order to examine the buckling and postbuckling of the cylindrical tanks. Herein, post-fire was introduced at different temperatures (150 C-600 C). Ten laboratory specimens in two groups with verified temperatures, under external pressure, are examined. The models were designed to demonstrate how repairing steel tanks, which are damaged by fire, by using carbonfiber-reinforced polymer can recover lost capacity. The results of testing under different theories and codes were compared. This study shows that the initial buckling load of the temperature group increased by 30.82% to 57.09% compared to the temperature without-CFRP group. The overall buckling load of the temperature group increased by 37.01% to 67.74% compared to the temperature without-CFRP group. The collapse load of the temperature group increased by 27.04% to 52.64% compared to the temperature without-CFRP group. And using carbon-fiber-reinforced polymer on models, which are damaged by fire, can be an improvement behavior for the buckling and post-buckling specimen tests.
