Post-tensioned vs reinforced concrete slabs in the UAE
When does a PT flat slab beat a conventional RC slab on a UAE building, and when does it not? The trade-offs, in plain engineering terms.
Read the guide →Bonded vs unbonded post-tensioning: how to choose
Both systems are used across the GCC. Here is how they differ in behaviour, durability, construction and long-term flexibility.
Read the guide →PT slab design checklist (ACI 318-19 and PTI)
The checks a two-way post-tensioned slab design should show, in the order a reviewer looks for them. Use it to review a package or to prepare one.
Read the guide →PT stressing: elongation tolerances and records
Measured elongation is the main field evidence that a tendon carries the force the design assumes. How it is calculated, checked and recorded.
Read the guide →Openings and coring in post-tensioned slabs
Cutting a PT slab is not like cutting an RC slab. A cut tendon can lose prestress over a whole strip of floor. How to plan openings, coring and fixings safely.
Read the guide →Prestress losses and elongation calculation
Stressing data on a PT drawing comes from a losses calculation. How friction, anchor set and long-term losses are worked out, and how calculated elongation follows.
Read the guide →PT flat slabs vs banded beam slabs
The two most common post-tensioned floor layouts, compared: where each one saves thickness, formwork and time, and what drives the choice.
Read the guide →Anchorage zones and bursting reinforcement in PT slabs
The concentrated force at a PT anchorage spreads into the slab through a zone of high tension. How bursting reinforcement is sized and detailed.
