The ACI approximate method, which is also called the simplified method of analysis, is presented by ACI 318-19, section 6.5 to analyze continuous beams and non-prestressed one-way slabs. It is derived by elastic analysis, considering alternative placement of live load to produce maximum positive or negative moment at critical sections. The approximate moments and shears, found by using ACI simplified method, give reasonable values for the stated conditions if the continuous beams and one-way slabs are part of a frame or continuous construction.
