“…In her study on the mechanics of flying buttresses in the case of the Mallorca Cathedral, Fuentes [50] first provided an overview of the structural behaviour of flying buttresses within the framework of limit analysis. She then analysed the deformations and cracks of flying buttresses in the Mallorca Cathedral and studied problems such as sliding of flyers" head and different solutions adopted for them throughout history.…”

A buttress is a crucial element for vaulted and domed masonry structures. In this study, after reviewing the buttress forms in historical masonry architecture, previous studies on masonry buttresses are summarized. Then, some ideas for potential studies on masonry buttresses are presented. Finally, the effectiveness of an idealized tree buttress-shaped buttress in supporting masonry structures against seismic forces is investigated. The results indicate that a concave parabolic buttress provides structures with a higher resistance than a buttress with an idealized shape of tree buttresses.

“…They came to the conclusion that, with the increase of architects' awareness about the structural importance of buttresses over time, they had emphasized more and more the technical aspect of this element in their structures. Fuentes (2018) after accurately surveying the Mallorca cathedral, she used the theoretical framework of limit analysis to analyse the distortion and sliding movements observed at some flying buttresses of the cathedral. It was concluded from the study that, flying buttresses have a fundamental role in the stability of the structure, although some of them experienced various problems over time.…”

In historical masonry structures having vault, dome and high walls, for safety against gravity, wind and earthquake loads, buttresses are crucial elements. This study aims to investigate the effect of buttress form on the transverse seismic resistance of high masonry walls. For this purpose, a real historical masonry structure covered by a barrel vault, and has a simple and regular plan and elevation shape was considered. From a slice of this structure, a calculation model and a basic model were created. For the masonry, macro-modelling approach was used. Nonlinear static analysis method was adopted, and finite element modeling and calculations were carried out using the Abaqus program. Firstly, on the calculation model the effect of buttress depth on transverse seismic resistance was investigated, and it was seen that the resistance is almost linearly related to the buttress depth. Then, two groups of analyses were performed on the models obtained by mounting different buttress forms to the basic model. In the first group, the volumes of the buttresses were kept equal, and in the second group their base depths and thicknesses were taken equally. At the end of these analyses, by comparing the base shear forces obtained for the models, the effectiveness of buttress form on the transverse seismic resistance has been determined and evaluated. The results revealed that the model with curvilinear concave buttresses in the first group analyses and the model with semi-cylindrical buttresses in the second group analyses have the highest seismic resistance.

“…Furthermore, the usual assumption that the masonry possesses unlimited friction capacity can lead to non-conservative predictions of stability; e.g. even though a line of thrust can be identified that fits entirely within the masonry, sliding failure at the head of a flying buttress may lead to premature failure [26,27]. Premature, friction-induced, failure may also arise in multi-ring arches [28].…”

Application of thrust layout optimization to masonry structures

A new automated analysis procedure designed to overcome limitations of the traditional thrust line analysis method for masonry gravity structures is presented. The procedure, termed thrust layout optimization (TLO), is capable of automatically identifying admissible thrust lines in masonry gravity structures comprising general arrangements of masonry blocks. The procedure employs a modified truss layout optimization with transmissible loads formulation, which means that an initial thrust line layout does not need to be specified in advance. Highly visual output is generated, allowing areas where tensile strength has been implicitly assumed to be clearly identified, which is beyond the scope of traditional thrust line analysis. Also, sliding failures can be modelled without difficulty. Finally, examples are used to demonstrate the efficacy of the TLO procedure; these show that thrust line bifurcations can be automatically identified in problems involving openings, and that there is no need to estimate the ineffective area in buttress wall problems, both issues for the traditional thrust line analysis method.
