Two tall reinforced concrete chimneys, Stacks 25F-5 (115 m) and 36F-5 (107.5 m), were subjected to strong ground motion during the August 17, 1999, Marmara earthquake. Stack 25F-5 failed while Stack 36F-5 survived. Both stacks were designed in accordance with ACI 307-69. This study reports the earthquake parameters, the ground motion measured within 3 km of the stacks, and the structural properties of the stacks. Evaluation of the response bounds of the stacks leads to the conclusion that the region of flexural yielding remained at the base of Stack 36F-5 while it was at a level approximately 35 m above base for Stack 25F-5 because it had a large penetration extending from 30 to 35 m. The collapse of Stack 25F-5 was not due to lack of strength caused by design or material deficiencies but was due to the presence of reinforcing-bar splices in the region where flexural yielding occurred.
