Strengthening and Softening of Ferrite+Pearlite Steels Produced by Thin Slab Casting and Rolling

Fu Jie,Wu Huajie,Liu Yangchun

Strategic Study of CAE 2008, Volume 10, Issue 4, Pages 65-72

Abstract:

Based on the principle of the integrated strengthening of steel, the strengthening and the softening of HSLC steel have been studied by controlling the precipitation of carbon in steel around A1 temperature. The results show that strength of HSLC steel produced by TSCR can be further increased. By using temper-slow cooling, σ_s of HSLC steel(ZJ330) produced by TSCR can be decreased from 344 MPa to 225 MPa to meet the requirement of producing basal plate for cold rolling. Problems about ferrite rolling, ultra fine grain steel and a possible new type building materials have been discussed.

Punching of reinforced concrete slab without shear reinforcement: Standard models and new proposal

Luisa PANI, Flavio STOCHINO

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 5, Pages 1196-1214 doi: 10.1007/s11709-020-0662-z

Abstract: Reinforced concrete (RC) slabs are characterized by reduced construction time, versatility, and easier space partitioning. Their structural behavior is not straightforward and, specifically, punching shear strength is a current research topic. In this study an experimental database of 113 RC slabs without shear reinforcement under punching loads was compiled using data available in the literature. A sensitivity analysis of the parameters involved in the punching shear strength assessment was conducted, which highlighted the importance of the flexural reinforcement that are not typically considered for punching shear strength. After a discussion of the current international standards, a new proposed model for punching shear strength and rotation of RC slabs without shear reinforcement was discussed. It was based on a simplified load-rotation curve and new failure criteria that takes into account the flexural reinforcement effects. This experimental database was used to validate the approaches of the current international standards as well as the new proposed model. The latter proved to be a potentially useful design tool.
