An investigation on connection points in timber reciprocal frame structures

Reciprocal frame structures can be defined as systems consisting of discontinuous short beams, where there is no primary/secondary load-carrying distinction between elements such as columns and beams. In this study, where timber reciprocal frame structures are examined, the subject is handled through connection details. The aim is to determine the distinguishing features of reciprocal frame structures from other construction systems, to examine the connection details of the elements in timber reciprocal frame structures and to discuss the parameters affecting these details, to analyze and compare the nodal point solutions in pavilion structures built with these structures, and to put forward a study that can be a guide in the Turkish literature. In the literature section where a comprehensive review research was conducted, information about timber reciprocal frame structures was provided. In the analysis study, 7 examples of pavilions built between 2012-2019, which were obtained by scanning from written and visual sources such as magazines, books, articles, papers, theses, internet, etc., were analyzed. The examples were analyzed and evaluated through the general information of the building, grid layout and connection point, and the table created from various subheadings within the scope of these titles. As a result of the study; it is thought that one of the main factors in detail solutions is the type and form of module element in the grid layout, while other data such as engagement length, number of layers, cover element are secondary data affected by the form of element type. It has been seen that the advantages and disadvantages provided by various features such as production, rigidity, assembly and disassembly, reuse, aesthetic appearance of the connection detail have an important place in the formation of the structure.
