Abstract:
When slenderness ratios of load-bearing reinforced concrete walls resting on either continious or isolated footings exceed the limits of ACI 318-71 (klu/r 100), a detailed evaluation of slenderness is needed. Using numerical analysis procedures, a systematic accounting of the various factors affecting the behavior of wall panels is presented here, based on a column model of the panel. Also presented in this paper is a typical design aid of a slender wall having a thickness of 5 1/2 in. (14 cm) and resting on continious footings. A rational means of evaulating the effects of isolated footings on the ultimate capacity of the slenderness walls is also indicated along with a design example.
