The mechanical response of post-tensioned glass beams is explored in this paper. This is done through bending experiments on post-tensioned glass beam specimens with either mechanically anchored or adhesively bonded steel tendons by which a beneficial pre-stress is inflicted on the glass beams. In addition, reference beams with identical geometry but without tendons are tested. From the results...

Data collected from shake table tests of two, approximately one-third scale, two story flat plate frames utilizing shear reinforcement, as well as data from prior tests, were evaluated to assess the inter-story drift ratios when punching failures occur for reinforced concrete and post-tensioned slab-column connections with and without shear reinforcement. The drift ratios at punching for the sh...

From among the several types of slabs, there is uncertainty about most cost-effective one for structures with short, medium, and long spans. A study comparing cost solid, flat, hollow block (HB), post-tensioned (PT) slabs 4, 6, 8m spans was conducted using SAFE software. For each span length, total quantities concrete steel bars were found compared 4 slabs. Then, bars, concrete, blocks, tendons...

This article evaluates and compares the punching shear behaviour of unbonded prestressed concrete (UPC) slab - concrete-filled steel tube (CFT) column connections/joints with that reinforced (RC) connection – CFT connections. The experimental program was carried out on five large-sized samples, including three UPC samples two RC samples. Steel plate details were utilised to increase bond betwee...

Since, it is essential to provide homeless people by the earthquake with safe, habitable accommodation repairing medium and slight levels of damage at the connection parts should be undertaken. In order to prove that a repaired connection was sufficiently strong, a precast beam to column post tensioned connection was tested in three phases. In phase one, the middle level damage was observed at ...

Due to lack of the proper and well behavior of steel moment-resisting connections subjected to the great and major earthquakes, excessive researches have been conducted to mitigate the damages on the primary elements and connections. Therefore, elimination of residual drift and increasing the plastic rotation capacity for the connectors in the panel zone are required. The main purpose of this s...

As PT floor slabs become thinner, a doubt about its vibration behavior and comfort of occupants arises. This paper investigates several approaches for determining the post-tensioned human induced vibrations which can give high accuracy be considered as simple tools guide designers. It also studies with different span length, thicknesses relates response to natural frequency floor. The results s...
