SLENDER RC COMPRESSED MEMBERS IN BIAXIAL BENDING

A method is presented for the "exact" nonlinear analysis of reinforced and prestressed concrete slender members subject to biaxial bending. The main feature of the method is the procedure that analyzes the stress-strain state of sections, under given axial force and biaxial moment. The outlined procedure, applied to a number of selected cross sections in the structure, allows an overall iterative procedure to find the solution of the structural problem for given loads. In fact, by integrating the deformabilities, the coefficients for the compatibility equations at the freed end are built up, while the integration of the curvatures yields the deflections, i.e. , the right-hand side of the equations themselves. The analysis of a 165-m bridge pier (prestressed) under earthquake simulating forces is given as an example.
