This paper presents a new technique to design RC columns of the rectangular section, subjected to axial compression and uni- or biaxial bending. Distributed bars around the perimeter are considered as an equivalent thin tube. Using the same steel area for two separate couples of axial compression and uniaxial bending is a trick to solve the equilibrium equations for the optimum steel ratio between faces b and h.

This paper analyzes the effect of temperature on steel fibers pull-out mechanism from a high strength concrete matrix and its contribution to the residual mechanical behavior of Steel Fiber Reinforced High Strength Concrete (SFRHSC). Pull-out tests of straight and hooked end fibers and uniaxial tension tests on the fiber filaments exposed to room and high temperature (300 C, 375 C and 475 C) were performed. Additionally, two SFRHSC incorporating 30 kg/m3 and 60 kg/m3 of hooked end steel fibers and a plain High Strength Concrete (HSC) exposed to the same temperatures were studied.
