Robert Park was a New Zealand structural engineer and a professor at the University of Canterbury. His primary contribution to civil engineering lies in . While many engineers focus on beams and columns, Park realized that slabs — particularly floor slabs in moment-resisting frames — play a critical, and often dangerous, role during seismic events.
Reinforced concrete slabs are the unsung heroes of our buildings. They transfer gravity, brace walls, and—if designed poorly—can trigger progressive collapse during earthquakes. Robert Park gave us the language and mathematics to understand slabs not as simple plates, but as complex, ductile, force-resisting systems.
Use these (but avoid pirate sites):
Unlike elastic methods, Park championed for slabs. This method assumes that at failure, a slab forms plastic hinges along lines (yield lines), creating a collapse mechanism. By equating internal work done by the yield lines to external work done by the loads, you find the ultimate load capacity.

Park was among the first to quantify how tensile reinforcement in a slab, running parallel to a beam, shifts the neutral axis and increases the beam’s flexural strength. However, this extra strength comes without extra ductility. In a seismic event, the slab yields before the beam’s intended plastic hinge forms. This leads to that can damage columns (strong-beam, weak-column behavior).

"Reinforced Concrete Slabs" by Robert Park and William L. Gamble is a foundational textbook, now in its second edition, that provides comprehensive coverage of slab behavior, elastic theory, yield line theory, and design methods. First published in 1980, the text offers in-depth analysis of serviceability, crack control, and modern design approaches according to the American Concrete Institute (ACI) code.
