A new eight-node Reissner-Mindlin plate element is developed with a special interpolation within the element. This special interpolation is an extension of the element boundary interpolation that employs Timoshenko beam function for the boundary segm...

A stiffened plate analogy for plate-and -beam structures (2006)
Conference Proceeding
Kuang, J. S., & Zhang, J. H. (2006). A stiffened plate analogy for plate-and -beam structures. In Joint International Conference on Computing and Decision Making in Civil and Building Engineering

The current design practice of plate-and-grid structures in buildings, such as waffle slabs and ribbed plates, is relied largely on code-specified approximate methods, and the deflection of the system is rarely evaluated owing to the complexity of ca...
