Abstract
This paper presents a methodology, based on Heyman’s safe theorem of limit analysis for masonry structures, to allow for the design and analysis of arches both unstrengthened and strengthened with composite materials. More specifically, we propose an extension of the Thrust Line Analysis to account for the expansion or contraction of the geometric domain of the thrust line able to include the effects of the limited compressive strength of masonry as well as the tensile strength and the delamination ruptures of the composite material.
The influence of each one of these issues on the size of the admissible domain, evaluated iteratively as a function of the internal forces, is numerically investigated and discussed.
期刊介绍：
The past few decades have seen outstanding advances in the use of composite materials in structural applications. There can be little doubt that, within engineering circles, composites have revolutionised traditional design concepts and made possible an unparalleled range of new and exciting possibilities as viable materials for construction. Composite Structures, an International Journal, disseminates knowledge between users, manufacturers, designers and researchers involved in structures or structural components manufactured using composite materials.
The journal publishes papers which contribute to knowledge in the use of composite materials in engineering structures. Papers deal with design, research and development studies, experimental investigations, theoretical analysis and fabrication techniques relevant to the application of composites in load-bearing components for assemblies, ranging from individual components such as plates and shells to complete composite structures.
