As tilt-up wall panels become taller, temporary erection bracing reactions increase. If these reactions are applied to a floor slab designed for service loads only, the slab may be too thin to resist the sliding and uplift components.

Structural engineers often strive to optimize the cost of structures by minimizing the sizes of structural members. Minimizing the size of concrete members, however, can lead to unintended consequences that may defeat the global goal of minimizing overall construction cost. It’s therefore important to step back and consider how the individual components interact.

Before the ACI Spring 2007 Convention, the Technical Activities Committee (TAC) selected 51 Chairs for ACI technical committees and TAC subcommittees.
