Abstract

Constraints are used widely for linear structural analysis in professional software, but some ofthem may be neglected in nonlinear analysis while using general FEA software. Two kinds of constraints, include panel zone at beam end and top alignment of beam and slab, are analyzed by numerical method. Numerical example shows that results with both kinds of constraints being taken as the reference value, the model only with panel constraints would amplify the structural stiffness improperly, the model without any of these two constraints would underestimate both damage of beam ends and floor drift angle at structural bottom, and top alignment of beam and slab which is seldom considered in engineering can improve the numeral precision effectively.
