Reinforced Concrete Tilt-Up Wall Panel Analysis and Design (ACI 318-14 - ACI 551)
Tilt-up is form of construction with increasing popularity owing to its flexibility and economics. Tilt-up concrete is essentially a precast concrete that is site cast instead of traditional factory cast concrete members. A structural reinforced concrete tilt-up wall panel in a single-story warehouse (big-box) building provides gravity and lateral load resistance for the following applied loads from three roof joists bearing in wall pockets in addition to the wind:
Roof dead load | = 2.4 kip per joist |
Roof live load | = 2.5 kip per joist |
Wind load | = 27.2 psf (Out-of-Plane) |
The assumed tilt-up wall panel section and reinforcement are investigated after analysis to verify suitability for the applied loads then compared with numerical analysis results obtained from spWall engineering software program from StructurePoint.
