Design and assessment of concrete structures with strut-and-tie models and stress fields
From simple calculations to detailed numerical analysis
The introduction of strut-and-tie models in fib Model Code 1990 as a design basis for discontinuity regions constituted a significant step toward promoting consistent design methods for reinforced concrete structures. In fib Model Code 2010, the scope was broadened through the st

Conical shell edge disturbance
An engineer's derivation
Because a rigorous bending theory for thin shells of revolution is complicated, attempts have been made for reliable approximations of the edge disturbance problem under axisymmetric loading. A well-known one was published by Geckeler [1, 2], who obtained his approximation by mat

Donnell published in 1933 an elegant and rather simple differential equation for the stress analysis in circular cylindrical shells. The civil engineering structural mechanics group in Delft has a long and strong experience in the fifties and sixties of last century in working wi
