Abstract:
The use of alternative design approaches that deviate from current ACI 318 slender wall provisions can have potential pitfalls that result in an inadequate slender wall (or tilt-up wall) design. Some of these deviations include substituting alternate equations such as an inappropriate effective moment of inertia or incorrect modulus of rupture into the approved ACI 318 methodology, using a superseded ACI 318 standard, or replacing the approved ACI 318 methodology with an inappropriate finite element model. Some of these deviations can yield particularly poor results when methods only appropriate for service level deflections are used with strength design equations for second-order P-D analysis.
