This publication provides the most recent examine findings of the short constructing purposes of fracture mechanics to concrete buildings. Key papers from prime specialists within the box describe present and new modelling recommendations within the research of fabrics and buildings. The e-book explains the sensible software of fracture mechanics to structural modelling, bending, shear, bond and anchorage. The complaints of this RILEM Workshop may be a huge reference for these engaged in layout, improvement, study and instructing within the box of concrete buildings.

Sample text

The assumptions made in this type of modelling are in agreement with the current experimental results. CONCLUSIONS Results are presented of mixed mode I and II tests of concrete. A shear-like load was applied to a specimen after it was pre-cracked to a prescribed axial crack opening. The results indicate that the response of the specimens upon shearing is governed by the development of a rotated principal stress state, especially for very small axial crack openings. Due to this rotation of principal stresses, diagonal cracking (under tensile shear) or splitting of compressive struts (under application of compressive shear) was observed in the 34 ANALYSIS OF CONCRETE STRUCTURES Fig.

Apparently the fracture patterns and nonlinearity are a function of the size of aggregates or voids. Fracture Mechanics Based Study In order to determine the criterion for crack initiation and propagation, a simpler specimen geometry was adopted. Thin rectangular slabs were cast in mortar matrix at different orientations to study the effect of interface inclination to the fracture phenomena. Specimens shown in Figure 2 were made of mortar with a 1: MIXED MODE FRACTURE IN COMPRESSION 51 Fig. 1a.

Chapman & Hall, (1990). HASSANZADEH Lund Institute of Technology, Sweden Abstract A testing arrangement has been developed in order to determine the fracture process zone properties, affected by simultaneously applied normal and shear displacement. The testing arrangement makes it possible to perform stable displacement-controlled mixed-mode tests according to any arbitrary displacement path. The paper presents the testing arrangement and discusses a few aspects of the determination of the fracture zone properties.
