Domes are elegant and economical structures used in covering large areas. They are built in various forms. According to their form, they are given special names such as lamella, network, and geodesic domes. In this paper, optimum topological design algorithm is presented that determines the optimum number of rings, the optimum height of crown and tubular section designations for the member groups of these domes. The design algorithm developed has a routine that generates the data required for the geometry of these domes automatically. The minimum weight of each dome is taken as the objective function. The design constraints are implemented according to the provision of LRFD-AISC (Load and Resistance Factor Design-American Institute of Steel Constitution). The optimum topological design problem that considers these constraints turns out to be discrete programming problem. Improved harmony search algorithm is suggested to determine its optimum solution. The design algorithm also considers the geometric nonlinearity of these dome structures. Design examples are presented to demonstrate the effectiveness and robustness of the design optimization algorithm developed.

Optimum topological design of geometrically nonlinear single layer latticed domes using coupled genetic algorithm
Saka, M. P. (2007-11-01)
Single layer latticed domes are lightweight and elegant structures that provide cost-effective solutions to cover the large areas without intermediate supports. The topological design of these structures present difficulty due to the fact that the number of joints and members as well as the height of the dome keeps on changing during the design process. This makes it necessary to automate the numbering of joints and members and the computation of the coordinates of joints in the dome. On the other hand the ...
Optimum design of double-layer grid systems: comparison with current design practice using real-life industrial applications
Aydıncılar, Yılmaz; Hasançebi, Oğuzhan; Department of Civil Engineering (2010)
Double-layer grid systems are three-dimensional pin-jointed structures, which are generally used for covering roofs having large spans. In this study, evolution strategies method is used to optimize space trusses. Evolution strategies method is a type of evolutionary algorithms, which simulate biological evolution and natural selection phenomenon to find the best solution for an optimization problem. In this method, an initial population is formed by various solutions of design problem. Then this initial po...
Optimum geometry design of geodesic domes using harmony search algorithm
Saka, M. P. (2007-12-01)
The optimum geometry design of geodesic domes presents difficulty due to the fact that the height of the dome keeps on changing during the design process. This in turn makes it necessary to automate the computation of the coordinates of joints in the dome when the height of crown changes. The algorithm presented in this study carries out the optimum geometry design of single layer geodesic domes. It treats the height of the crown as design variable in addition to the cross-sectional designations of members....
Seismic behavior of autoclaved aerated concrete low rise buildings with reinforced wall panels
Gökmen, Furkan; Binici, Barış; Canbay, Erdem (Springer Science and Business Media LLC, 2019-07-01)
Reinforced Autoclaved Aerated Concrete (AAC) wall panels are more commonly used to construct load-bearing walls in low-rise prefabricated buildings located in seismic zones. In the scope of this study, the seismic response of buildings constructed with reinforced AAC wall panels was investigated. To this end, an in situ test was conducted on a two-story test building under reversed cyclic displacement excursions. It was determined that the test building could carry a lateral load of 60% more than its weight...
Creep modelling study of a surface support liner
Güner, Doğukan; Öztürk, Hasan (2018-06-24)
Surface supports are widely used in underground excavations. Since conventional surface support liners have inherently-brittle characteristics and require longer curing period, an alternative support system using polymer based surface support liner, thin spray-on liners (TSLs), has been observed to have a promising ductile and fast-curing potential for underground operations. TSLs can exhibit a good performance for highly-stressed, deep, rock bursting conditions as well when used together with rock bolts an...
