Some experiments on headed stud connections for precast concrete panels under monotonic and cyclic shear loadingBischof, Max January 1978 (has links)
The research on headed stud connections described in this thesis forms a part of a larger program with the objective of predicting the behaviour of precast concrete panel buildings under earthquake loads.
The first objective of this research is to produce experimentally a concrete failure of the connection and to compare the actual failure load to the one predicted by the PCI design handbook. The tests show that the PCI shear-tension interaction equation for single headed studs can be used for the prediction of a concrete failure for a connection of the type tested. This method yields conservative results if a special equilibrium model for the determination of the stud tension force is used, and the bearing capacity of the structural steel angle on the concrete is neglected.
The second objective of this research is to determine the bearing capacity of a reversed angle connection. Experiments show that this bearing capacity is equivalent to a force resulting from a stress equal to the concrete strength uniformly distributed over the concrete area enclosed by the structural steel angle 2" x2". Furthermore, the location of this force can be assumed in the center of gravity of the structural steel angle shape, regardless of whether or not there is an endplate present. / Applied Science, Faculty of / Civil Engineering, Department of / Graduate

Laboratory test procedures to predict the thermal behaviour of concrete.Gibbon, George James January 1995 (has links)
A thesis submitted to the Faculty of Engineering, University of the Witwatersrand,
Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy / The cracking of mass and structural concrete due to thermal stress is a major problem
in the concrete construction industry. Concrete will crack when the thermal
stress exceeds tbe tensile strength of the concrete, Decisions on the type of concrete
mix, cooling facilities and construction techniques to be used in the erection of a
concrete structure can only be made if the thermal behaviour and strength of the
concrete can be predicted during hydration. This thesis describes the development
of a low cost, computer controlled, adiabatic calorimeter to determine tlte heat of
hydration and a probe to determine the thermal conductivity or concrere samples.
The main thrust of this thesis is the development of the thermal conductivity probe
which, for the first time, can measure the thermal conductivity of concrete through
all stages of hydration. A thermal model was also developed to verify the results,
and the use of the calorimeter for temperature matched curing tests is also discussed.
Results, obtained from the test procedures described, will provide far more accurate
predictions of the temperatures in concrete structures than was possible in the past. / Andrew Chakane 2018
