“…The results showed that the shear bearing capacity of the U-shaped UHPC formwork for the composite beam was significantly improved. Also, several studies [16,17] showed that applying a layer of ECC could increase the maximum load and impact the minimum reinforcement requirements. Carlos Zanuy [18] conducted an impact experiment on RC beams strengthened with a thin layer of ECC.…”

Engineered Cementitious Composite (ECC) was used in the prefabricated shell of a precast composite beam, and the validity of the ECC in the precast monolithic composite beam’s flexural performance was studied. Flexural performance tests were conducted on six specimens to analyze their failure state, failure mechanism, bearing capacity, and deformation capacity. Compared with the Reinforced Concrete (RC) prefabricated shell composite beam, the ECC prefabricated shell composite beam showed a higher bearing capacity and lower damage degree. The yielding load of specimen PSMCB−1 increased by 5.6%. The maximum load of specimen PSMCB−1 reached 256.6 kN, having increased by 8.1%. When the tests stopped, the maximum crack width of specimen PSMCB−1 was 4.1mm, while the maximum crack width of specimen PSMCB−6 reached 9.0 mm. The ECC material in the prefabricated shell also delayed the yielding of the steel bars in the shell.

The investigation pertains to the coating utilized in single-story industrial buildings. Frame constructions with spans of 24, 30, and 36 meters are examined, employing wood-based elements as rafter structures. The reinforced concrete rafter structures exhibit a pitch of 2-3 meters and are configured in the shape of an I-beam. The truss structures along their length are subdivided into seven sections, featuring variable lengths, flange widths, rib thicknesses, and cross-section heights. Deflection calculations consider the nonlinearity of concrete and reinforcement deformations, adhering to prevailing building codes. The elastic solutions method is employed in conjunction with the finite difference method. The proposed coating designs are distinguished by their ease of manufacturing, transportation, and element installation. The wood-composite rafter structure boasts a lower mass compared to reinforced concrete elements, facilitating installation with a lightweight crane and overall diminishing the coating's weight without compromising its structural integrity. Several beam characteristics for spans of 24, 30, and 36 meters include respective mid-span heights of 1.2 meters, 1.4 meters, and 1.5 meters; volumes of 8.23 cubic meters, 9.25 cubic meters, and 10.6 cubic meters; and weights of 19.8 tons, 22.2 tons, and 25.4 tons. The proposed solution allows for the integration of bending moment and stiffness diagrams for the rafter beam configuration.
