WebThe 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. WebArea Moment of Inertia. The second moment of area, more commonly known as the moment of inertia, I, of a cross section is an indication of a structural member's ability to resist bending. (Note 1) I x and I y are the …
