“…Prestressed concrete has various advantages in comparison to traditional reinforced concrete. Prestressing technique increases the tensile and flexural capacity of the concrete elements in addition to preserving the sustainability concept through the reduction in the usage of materials and sequentially the embodied energy [1][2][3]. Prestressed concrete elements can be either post-or pre-tensioned: tendons of pre-tensioned elements are stressed before the concrete casting, while in posttensioned ones, they are stressed after pouring and hardening of concrete.…”

Post-tensioned slabs are tested in order to investigate the tendon stress at ultimate limit state in case of using bonded and unbonded tendons. The main objective is to compare the values of the mentioned tendon stress to those predicted by ACI 318-19 based on empirical equations for unbonded tendons and based on strain compatibility for bonded ones. The experimental program will be carried on six one-way slabs in four-point flexural loading. Details of the tested slabs and the test set up are presented in this paper. The results of the test carried showed an excellent correlation where almost all of the slabs experimental test results were equal to the theoretical results with a very minor difference around 10 percent.

“…Bonded tendons (Figure 1) are seven-wires strands inserted inside a plastic or steel duct, and after stressing the strands, grout is injected to fill the duct. Unbonded tendons (Figure 1) are made up of greased seven-wires strands covered with plastic sheathing [2]. Unbonded tendons have many advantages compared to bonded ones such as better corrosion resistance, ease of construction, flexibility and faster construction rate [4].…”

“…El uso de elementos postensados tiene ventajas como el ahorro de recursos, lo que implica un diseño sustentable como en edificios de gran altura. Respecto al diseño estructural, existen casos como lo reporta Süleymanoğlu H et al [3] que el factor de agrietamiento de las losas se puede tomar un valor de 0.25, esto implica que se debe tomar 25% de momento de inercia bruta (Ig) de la losa postensada en el sistema lateral. Cabe destacar que este porcentaje de Ig varía dependiendo el proyectista, ya sea por su práctica o ensayos realizados tomando en cuenta las derivas y las fisuras que tienen las losas considerando los códigos de cada país, reportado en el survey realizado por el comité técnico ACI 375 [2].…”

Post-tensioned slabs are being used lately with greater regularity, however, there is some ignorance about their use participating within the structural system resistant to lateral forces such as those produced by the earthquake or the wind. In this work post-tensioned slabs are used in two directions as floor systems in high buildings with rigid core, that is to say that they have structural walls in the middle zone of the building. Those posttensioned slabs were modified the gross moment of inertia (Ig) to study the seismic behavior of the tall buildings as well as the response of those slabs. This study is validated with several computational models of buildings, in which a slab thickness is proposed in order to satisfy the maximum drifts of the tall buildings established by the national standard, varying the moments of inertia of these post-tensioned slabs. It also involves the modification of the resistance to compression of the concrete (f'c) of the slabs and vertical elements, as well as the thicknesses of structural walls. The result of this study is the obtaining of thickness of post-tensioned slab with respect to the variation of the capacity to compression of the concrete (f'c) distributed in the building, thickness of walls in rigid core and the percentage of cracked moment of inertia of the post-tensioned slabs. Punching was also checked on the post-tensioned slabs. Keywords-post-tensioned slab, gross moment of inertia, high buildings, rigid core.
