Multi-Story Tilt-Up Wall Panel with Openings 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 multi-story tilt-up wall panel with openings in a building provides gravity and lateral load resistance for the applied loads from roof and floor joists.
The existing tilt-up wall panel in the following figure will be investigated to evaluate the as-built design to resist the applied gravity and lateral loads. The results, from ACI 318 procedure, will then be compared with numerical finite element analysis results obtained from spWall engineering software program from StructurePoint. Additionally, different modeling and analysis techniques using spWall software to investigate and design multi-story tilt-up wall panels with opening are discussed.
