Crack Analysis in Structural Concrete Theory and Applications

Crack Analysis in Structural Concrete Theory and Applications

As research scientists and practicing engineers working in the field of structural engineering and
whose responsibilities are almost exclusively confined to analyzing cracked concrete structures
for the safety evaluation and renovation design of today’s aging infrastructure, we have been
studying cracks in various concrete structures through crack analysis for more than a decade.
The structures that we have frequently encountered for crack diagnosis include tunnels, dams,
bridges, sewage pipes, and so forth, and we need to clarify the various mechanisms by which
cracks occur and evaluate the damaging effects that these cracks inflict on these structures. Crack
analysis is indispensable in answering these questions, and it is a fascinating field of study in
structural concrete.

This book is an outgrowth of my research in the broad field of fracture mechanics over a period of
twenty years, the past fifteen years of which I have spent focusing on a subbranch of the disci-
pline—that is, fracture mechanics of concrete. My late decision to focus on this field of study
was motivated by two factors, namely, a surging demand for crack analysis in structural concrete
and a keen personal interest in the subject. Compared with other mature engineering disciplines,
fracture mechanics of concrete is still a developing field that is wonderfully rich in scope and
diversity and full of challenging issues to be studied.
