A new approach for the interpretation of pressuremeter tests in sands is proposed that permits the determination of shear strength characteristics, dilatancy properties, and shear modulus from the analysis of pressuremeter test results. A relatively simple soil model has been developed that takes into account the contracting or dilating behavior of the soil, or both, during the pressuremeter cavity expansion. The soil is assumed to be an elastoplastic material with a nonassociated flow rule. To evaluate the proposed interpretation procedure, laboratory cavity expansion tests on Fontainbleau sand specimens have been conducted in a specially designed hollow-cylinder cell. The comparison between the sand properties (shear modulus, peak friction angle, dilation angle) derived from the cavity expansion tests and those obtained from conventional tests illustrates the applicability of the proposed interpretation procedure.

The report is divided into three sections:
1. The physical properties of FRC;
2. The areas where concrete durability is affected by the addition of fibers; and
3. A series of applications where FRC use resulted in beneficial durability.
The various properties addressed and the wide selection available in formulating matrix systems allow performancebased specification of concrete materials using fibers to
become a viable reality. The objective of this report is to provide a historical basis about current knowledge for concrete professionals to use in tailoring new, sustainable, and durable concrete mixtures.

There are many important
questions in the field of infilled frames, such as:
1. What are the negative and positive effects of infill walls in various types of buildings
(local and global)?
2. Where infills should be considered (in which type of structures, considering lateral
resisting system)?
3. When it is better to have interaction between frame and infill? In what type of
structures considering the number of stories?
4. When it is better to have a gap between frame and infill?
5. What is the state of the art in this field?
6. Comparing National and international codes, what is the state of the practice?
7. What are the suitable strategies to retrofit existing infilled frames?
The aim of this chapter is to answer some of these questions. A categorized discussion is
presented here to classify the problems solved or to be solved.
