“…The torsional behavior of beams can be modeled using finite element analysis or experimental testing. The torque-twist responses of normal-strength concrete beams with ferrocement "U" wrap (plain beams and reinforced concrete beams) with various types were tested and analyzed [23].…”

Structural elements are subjected to different types of loads, one of which is a torsional load. Due to the complexity of the analysis, torsion was not given much importance in earlier days. With stringent updates in codal provisions and due to architectural modifications, torsion is now considered one of the major parameters for structural design. The main aim of this paper is to analyze distressed elements due to torsion. It highlights different approaches, such as destructive and non-destructive processes, to be adopted to estimate the torsional parameters of a ferrocement “U” wrapped beam. The destructive method is the experimental determination of parameters, which is absolutely necessary. The non-destructive method includes an analytical method based on a softened truss model as well as a soft computing method. The soft computing method is based on the regression coefficient analysis method along with two recent optimization algorithms, i.e., (1) ARO (artificial rabbits optimization) and (2) DAOA (dynamic arithmetic optimization algorithm). The predicted results are found to be in agreement with the experimental values (destructive method). Lastly, the obtained results from both proposed methods are analyzed, and it is found that both algorithms can be utilized in any engineering problem to determine the global optimum value with corresponding input optimal settings. As the experimental method is time-consuming and expensive, analytical, and soft computing methods can be preferred over the experimental method.

“…Few analytical and experimental studies are found which quantify the torsional strength of FRP bonded full wrap [8][9]. But inaccessibility and extension of flanges over the web has necessitated strengthening the beams by "U" wrap rather than full wrapping [10]. Methods for quantification of torsional strength of "U" wrapped beams are found to be very few [11].…”

Designers are more interested in strength at cracking rather than ultimate strength. Still then beyond cracking, the structures are able to sustain more loads. So, determination of ultimate strength is an important parameter in design field. Evaluation of ultimate torsional capacity of high strength distressed beams with ferrocement “U” wrap has been presented here. The evaluation procedure involves experimental results, results obtained by analytical method. As the above two methods are not providing quick solution, rather than the first one is based on destruction of prototype structure for evaluation of strength. Other methods such as soft computing methods have been employed. Two methods MARS and WASPAS are employed here to compute the torsional strength of “U” wrapped beams. These two methods provide quick solutions to estimate the torque and twist at ultimate stage. Predicted values by these methods are within acceptable limits. At ultimate stage , the “U” wrapped beams are able to resist torque more than 41.37% than the unwrapped beams and a completely over reinforced beam resists 98.01% more than plain “U” wrapped beams. Under reinforced “U” wrap beams have undergone 23.9 times more twist than that of plain “U” wrap beams. This proves effectiveness of “U” wrap on periphery of distressed beams.

“…Torsion is a supreme aspect which is considered along with other basic structural actions. The torsional effects cannot be ignored in the present-day design due to (I) Large torsional moments tempted in structures and (II) Critical safety features used in project methods [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Retrofitting of distressed structures is a major concern worldwide for researchers particularly against torsion. Determination of torsional strength of retrofitted RC beams “U” wraps is again a difficult task. The experimental program is taken up with 30 rectangular beams tested under pure torsion. Torque of such a “U” wrapped RC beam with other dimension and material cannot be derived from these experimental results. To compute the same; analytical method based on softened truss model of Hsu is employed with modification on material properties. Both experimental and analytical methods are unable to provide a single equation to quantify the torsional strength. To overcome the same, soft computing method MARS and WASPAS method is employed in the present investigation. The methods are easy and time saving.
