SHEAR STREN GTH OF CIRCULAR REINFORCED CONCRETE COLUMNS
Author: Lisa Y. Choe | Size: 29 MB | Format:PDF | Quality:Unspecified | Publisher: The Ohio State University | Year: 2006 | pages: 77
In this research, the influence of parameters on the shear strength of circular reinforced concrete columns is investigated based on the evaluation of experimental data from numerous column tests. Key parameters investigated in shear strength model are the column aspect ratio, axial load, amount of transverse reinforcement, and deformation ductility demand. An examination of existing design equations reveals wide difference in predicted response. Also, the shear strength model for rectangular reinforced concrete columns proposed by Sezen et al. (2004) is used for evaluating whether it is applicable to predict the shear strength of circular columns. The proposed shear strength equation by
Sezen et al. (2004) is composed of additive contributions from concrete and transverse reinforcement, and is a function of displacement ductility. The model proposed by Sezen et al. (2004) is compared with contemporary code provisions and previously proposed models using the available column test data and is shown to result in improved accuracy.

A NEW MODEL FOR JOINT SHEAR FAILURE OF REINFORCED CONCRETE INTERIOR BEAM-TO-COLUMN JOINT
Author: Hitoshi SHIOHARA | Size: 725 KB | Format:PDF | Quality:Unspecified | Publisher: Journal of the School of Engineering, The University of Tokyo, Vol. XLV (1998) | Year: 1998 | pages: 30
The primary objective of this study is to point out an irrationality in the joint shear failure model, which is adopted in the most current design codes of reinforced concrete beam-to-column joint. To examine this issue, tests of twenty reinforced concrete interior beam-to-columnjoint failed in joint shear are reexamined. The data indicated that joint shear stress had increased in the most specimens, even after apparent joint shear failure starts, while beam moment decreases due to decrease of flexural resistance which is caused by reduction of distance between stress resultants in beam at column face. The cause of the deterioration of story shear is identified to be a degrading of moment resistance of joint, originated from a finite upper limit of anchorage capacity of beam reinforcements through the joint core. So a new mathematical model for joint shear failure is introduced to reflect this fact. The behavior of the
model is investigated and a new approach for the design of beam-to-column joint in seismic zone is proposed based on the prediction of the model.

This report presents the results of an experimental study investigating shear transfer mechanisms of column base plate details. This investigation is the first phase of a broader study whose aim is to develop improved design guidelines for column base plates. A review of existing design guidelines and published research reveals that shear transfer mechanisms in exposed base plates are not well understood, and methods to characterize
strength capacities in shear are not adequately supported by experimental data. To investigate shear transfer in exposed column base plates, seven large scale specimens were subjected to a combination of axial compression, axial tension and lateral shear deformations. The tests investigated three mechanisms commonly used for shear transfer in base plates, including (1) friction between the base plate and the grouted footing, with and without steel shim stacks (2) anchor rod bearing and (3) shear key bearing. The base plate tests are complemented by ancillary tests to characterize material properties.
Three tests which investigate surface friction indicate that the coefficient of friction between a steel base plate with mill scale and a grouted surface, with or without shim stacks, is 0.45. This value is lower than the design value of 0.55 recommended by the Steel Design Guide One, published by the American Institute of Steel Construction.

Connections of steel columns to concrete foundations may be loaded by combinations of
normal force, bending moment and shear force. Shear force will primarily be transmitted by
friction between the base plate and the grout layer to the concrete foundation. If the compression force is small, or if tension force is present, as may occur in slender high rise structures like towers and masts, the friction will be small or absent. Then, the anchor bolts will be loaded by shear force and bending moment. At the Stevin Laboratory of Delft University of Technology, experimental and theoretical research has been carried out on column bases loaded by combinations of shear force and tension force.
In the paper, the main results of this research programme are summarised. The test results are presented and the analytical model that was developed to describe the load deformation
behaviour.
