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 …

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 …

Compressive Membrane Capacity Estimates in Laterally Edge Restrained Reinforced Concrete One -Way Slabs
… capacities at the support and midspan hinge lines allow for a simple, and extremely accurate, estimate of the peak compressive membrane capacity using yield line theory.

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 …

Evaluation of Extended End-Plate Moment Connections Under Seismic Loading
… were used. The connections were designed using yield-line theory to predict end-plate yielding and the modified Kennedy method to predict maximum bolt force calculations including prying action. A displacement controlled loading history was used to load the specimens. The maximum moments …

Behavior of Connection with Beam Bearing on Bottom Flange of Girder
… Five girder specimens were loaded until yielding during the initial phase of the research. The analysis section consists of the yield line theory and finite element study that were used to develop a model to predict the collapse loads of the girder sections. These results from the model …

Elastic and ultimate behaviour of skew composite slab-on-steel girder bridges.
… stages of loading. In this work, both the nonlinear finite element method and the yield-line theory were employed in the theoretical analyses. The finite element method was used to study the behaviour and response of skew composite bridges in the elastic and post-elastic ranges of loading. The …

Evaluation of the Inelastic Rotation Capability of Flush End-Plate Moment Connections
… of the connections were calculated using yield-line theory to predict end-plate yielding and maximum bolt force calculations including prying action. Experimental results were also compared to previous research with regards to strength and stiffness. The inelastic rotation of connections …

Analytical and experimental investigation of a flush moment end-plate connection with six bolts at the tension flange
… frame construction. The limit states of plate yielding and bolt fracture were analyzed using yield-line theory to predict endplate thicknesses and a split-tee analogy to develop a method to predict bolt forces. Five experimental tests were conducted on four configurations within a matrix of …

Web crippling of hot-rolled beams at stiffened-seat connections
… web crippling of short-span plate girders. Yield-line theory and the mechanism solution were used to derive an expression for the web crippling capacity of a plate girder subjected to an interior patch load. The general form of this equation was then calibrated using available data to obtain …

Strength and Stiffness of Weak-Axis Moment End-Plate Connections
… of column web rotations, of the connections. Yield line theory was used to investigate the plastic strength of the column web. Several yield line patterns were examined. Analytical plastic moment strengths were very conservative when compared to the observed behavior of the column web. The …

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 …

Design of moment end-plate connections for seismic loading
… minimum end-plate thickness were developed from yield-line theory with prying forces included in the bolt tension forces. Stiffened end-plates, four-bolt wide connections and shimmed end-plate connections were valiations of the four-bolt connection tested. A325 and A490 bolts with internal strain …
