Finite Element Analysis Of Two-way RC Slab Under Linear Load

Two-way RC slab is the structural element which is most widely used in architecture engineering at present, and it has great effect on the safety and economy of buildings. In the practical project, there is a mature and perfect design method under the uniformly distributed loads. But there is a lack of systematic and complete analysis about mechanical behavior which is under the linear load at the present. Designers usually add the quantities of longitudinal reinforcement to consider linear load. As a result, it usually leads to a waste of material and shortage of reliability.In this thesis, finite element analysis software ANSYS is used for mathematic model of RC-slab which have different spans with finite elements and more accurate finite element analysis is done for the reinforce concrete slab. This thesis study on the influence of position and value of linear load, length-width ratio and thickness of two-way RC slab are considered. Formula of maximum moment which is in the center of RC slab is regressed. Some proper suggestion is taken about distributed steel of RC slab. At the meantime, equivalent distributed load which is different layout format of liner load is advised in the form of table. The thesis also systematically studies on mechanical behavior of RC slab and hidden-beam when there is a hidden-beam in the two-way RC slab, analyses the influence of mechanical behavior about RC slab with the change of ratio of reinforcement under the hidden-beam and thichess of reinforce concrete slab. Some suggestion for design of hidden-beam and RC slab is advised furtherly. All the principles and suggestions will make the designation of project under linear load more reasonable and economical.
