... design tables for slabs presented the most conservative value (about 67% higher than the load used to design the slab). This behavior occurs because the tables often give maximum values for design bending mo- ments and ... See full document

... With the construction of the models, an analysis of the standardized residues was performed. The collected data that generated standard- ized residues with higher than 3 module were eliminated from the analysis, ... See full document
