Design of Membrane Structure as a Temporary Roofing System

[摘要] Transactions of the VSB – Technical University of Ostrava, Civil Engineering Series, Vol. 21, Issue 2 (2021) pp. 90-95, DOI: 10.35181/tces-2021-0020 This paper concerns the results of research into the effect of the mechanical fracture parameters of inclusion material on the fracture response of specially designed cement-based composite specimens. These specimens of the nominal dimensions 40x40x160 mm with inclusion in the shape of prisms with nominal dimensions of 8x8x40 mm were provided with an initial central edge notch and tested in the threee-point bending configuration. The aim of this paper is to analyse the effect of the mechanical fracture parameters of inclusions material on the effective mechanical fracture parameters of cement-based composite. The results of this research indicate the dependence of the effective mechanical fracture parameters of cement-based composite on the Young’s modulus of inclusion material.
