Self-Compacting Concrete

By : Hajime Okamura and Masahiro Ouchi

Abstract :
Self-compacting concrete was first developed in 1988 to achieve durable concrete structures. Since then, various investigations have been carried out and this type of concrete has been used in practical structures in Japan, mainly by large construction companies. Investigations for establishing a rational mix-design method and self-compactability testing methods have been carried out from the viewpoint of making self-compacting concrete a standard concrete.

WIND-INDUCED NONLINEAR LATERAL-TORSIONAL BUCKLING OF CABLE-STAYED BRIDGES

By Virote Boonyapinyo, Hitoshi Yamada, and Toshio Miyata

ABSTRACT: A finite element approach to calculate directly the critical wind velocity for the nonlinear lateral-torsional buckling instability of long-span cable stayed bridges under the displacement-dependent wind loads is presented. An analytical modeling of wind-induced lateral-torsional buckling is formulated taking into account the three components of displacement-dependent wind loads as well as geometric nonlinearity. A combination of the eigenvalue analysis and the updated bound algorithm for wind velocity is applied to automatically calculate the critical wind velocity. The results show that the incorporation of the three components of displacement-dependent wind loads as well as the geometric nonlinearity in the analytical modeling of the lateral-torsional buckling instability results in significant reduction in the critical wind velocity compared with both the conventional non-linear torsional divergence and linearized lateral-torsional buckling.
