Abstract
This paper describes a new method for constructing concrete shells using
textile reinforced cement (TRC) composites as flexible formwork and tensile
reinforcement. By means of a case study on a synclastic concrete shell, which is
a compression-only structure under its self weight, the paper presents the analysis
of the TRC formwork on the one hand and the TRC reinforcement on the other
hand. The analysis of the formwork and the reinforcement is performed using the
finite element software Abaqus. For this synclastic shell, the formwork stage is
the deciding stage. Local buckling of the edges of the shell’s formwork is the
determining factor for the TRC thickness. For this reason, special attention is paid
to these edges and to solutions which decrease the needed TRC thickness.
Keywords: textile reinforced cement composite, flexible formwork, synclastic shell.
