For example, a column in a 3D frame must be proportioned to resist axial force and bending moments that act simultaneously. For such cases, seismic codes do not provide clear suggestions for the proper combination of sectional forces needed for the calculation of the longitudinal steel reinforcement. The objective of the present paper is the comparative evaluation of eight different methods of selection of the sectional forces needed for the calculation of the longitudinal steel reinforcement in concrete frame elements when the linear response history analysis is used. First, the eight methods are briefly presented. Then, a single-story symmetric building subjected to 15 strong earthquake ground motions is analysed. For each ground motion the longitudinal reinforcement at all critical cross sections is calculated using the eight aforementioned methods. Based on the results of the whole investigation, the following two general conclusions can be drawn: a) The required longitudinal reinforcement is significantly affected by the method used to select the design sectional forces in the frame elements and b) the differences in the results produced by the above methods range between 23% and 300%.
