摘要
A methodology was proposed to calculate the incremental deflection of reinforced concrete flexural members for the purpose of protecting nonstructural elements. The methodology is based on the long-term deflection calculation equation provided in the current Canadian standard, CSA A23.3-04, and takes into account realistic load application sequence during construction. Based on the proposed methodology, simple equations for calculating the incremental deflections were derived. The use of the proposed equations is demonstrated through a realistic design example. Implications of construction load and camber for deflection calculation and control are also discussed.
