Abstract:

To investigate the behaviour of precast tunnel lining segments subjected to concentrated loads on a small scale, laboratory tests on concrete prisms under partial-area loading in conjunction with numerical analyses were performed. Various parameters influencing the load-bearing and fracture behaviour of plain concrete (PC) and steel-fibre-reinforced concrete (SFRC) under concentrated loads are considered, including fibre properties (dimension, aspect ratio, tensile strength), fibre dosage and orientation, area ratio and eccentricity of load. The effects of these parameters on the ultimate bearing capacity, stress-displacement behaviour, failure mode and crack characteristics are analysed and discussed. Parallel to the experimental investigations, numerical simulations using a continuum coupled damageplasticity model for triaxially loaded cementitious material were performed. It is shown that the numerical analysis is able to realistically capture the structural behaviour and the crack pattern of partially loaded PC and SFRC specimens.

Abstract:

The theory of probability is used to solve the problem of forecasting the delfection of reinforced concrete beams. Nonhomogeneous Markov Processes are described. The development of a probabilistic method is presented in a manner which can be readily applied. In predicting deflections of reinforced concrete beams, a solution of empirical nature is used. The predictions show good agreement with labortary tests.

Abstract:

SP31 Contains seven papers and one committee report on applications of probabilistic principles to design of reinforced concrete structures. The first five papers were presented in a Symposium on Probabilistic Design as a part of the Annual Convention of the American Concrete Institute in Denver, Colorado, March 12, 1971.

Abstract:

Structural safety is analyzed by means of a simple model of the design procedure. All potential uncertainties which may affect the safety are classified in 9 groups of errors. The characteristics of three different measures of structural safety are briefly discussed and particular emphasis is given to a new yardstick for safety, the "coefficient of variation of a structural design."
