Reinforced Concrete Sections under Moment and Axial Load
A spreadsheet-based program for producing moment-curvature and moment-axial force diagrams Moment-curvature plots and moment-axial force interaction diagrams are essential tools for understanding the load-deformation behavior of structural elements. Moment-curvature plots readily illustrate stiffness, strength, and cross-sectional ductility, and allow the calculation of deflections after materials become nonlinear. Moment-axial...

Seismic Design Criteria for Slab-Column Connections
Two-way slabs without beams are popular floor systems because of their relatively simple formwork and the potential for shorter story heights. Earthquakes, however, have demonstrated that slab-column frames are vulnerable to brittle punching shear failures in the slab-column connection region and dropping of the slab, which are costly to repair....
