Yield-line analysis and experimental study of reinforced concrete slabs containing openings
… were measured during loading and the final yield pattern and ultimate load were compared to those predicted by simple and advanced yield-line theory. An analytical computer program was developed and is presented for quick evaluation of the ultimate load and collapse mode of many types of …

Análise limite de lajes via programação linear através do método dos elementos finitos
Based upon the Yield-Line Theory (Johansen, 1932) a non-oonventional finite element is formulated for the analysis of slabs whose oonstitutive law is defined through a moment-rotation curve at the section transversal to the yield-line. Thus only with the displacement perpendicular to the slab …

Flexural strength of circular monopole flange connections.
… A design example using T-stub analysis and yield line method is included. Using the yield line theory, the thickness required for stiffened connection is found to be 22% less than that for unstiffened connection. For the same flange thickness, stiffened connections are stronger by 68%. It is …

Simplified method for design or moment end-plate connections
… the strength of the end-plate, determined by yield-line analysis, or the strength of the bolts, determined by the semi-empirical Kennedy method. The calculations involved in the Kennedy bolt analysis incorporate prying action, yet are complex and extensive. This study presents a simplified …

Shear strength of reinforced concrete wall-beam structures: upper- bound analysis and experiments
… derived for a stringer model with a straight 'yield line'. Recently, evidence has emerged that the best single yield line between two rigid wall portions may well be curved and not straight. There are different stress states in yield lines and consequently three types of yield line are …

Four-bolt extended unstiffened moment end-plate connections
… The design procedures include the use of yield-line theory for determining the end-plate thickness and the so-called modified Kennedy method for determining bolt forces. This investigation extends these design procedures to include the four-bolt extended unstiffened moment end-plate …

Irregular Welded Rectangular Hollow Section Truss-type Connections
… one of the analytical models – a combined yield-line mechanism – is recommended to be used for the design of laterally offset RHS X-connections. For overlapped K-connections, the effect of hidden toe welds was investigated both experimentally and numerically. Five full-scale welded …
