“…This assumption is valid for the structures with one second main vibration mode or less, but with longer periods in very soft structures, the effects of next vibration modes should also be considered in analysis. [5,6] In this method, performance point of structure is determined by crossing the capacity spectrum and suitable demand response spectrum which is decreased due to nonlinear effects. [3,4] …”

Acceptance and popularity of space structure among architectures and designers is due to reasons such as: great spans covering, magnificent architecture, extremely low weight, the ease of building process, speed in installation, quality of response to earthquake, etc. Considering that usually large population live in space structured buildings, resistance and safety of the structures against destructive factors such as earthquake is very important. In this paper, we examine the effects of different geometrical parameters such as: type and shape of support on performance level of single grid layer of space structures and their performance at different risk stages are examined based on the regulations stated in Iranian Standard for Retrofitting of Existing Buildings. Since there is no acceptance criteria in international codes defined for determination of performance level (among Iranian code) in space structures, these criteria are suggested primarily. Finally performance points and levels of these structures are obtained by illustrating the capacity curves. Nonlinear static analyses (pushover) are carried out on the selected models using SAP and ANSYS software. Performance levels and capacity spectrums are obtained by FEMA and ATC40 bylaw.

Generation and Nomenclature of Tessellations and Double-Layer Grids

et al. 2012

The aim of this work is to establish a systematic methodology for generating automatically different tessellations and double-layer grids (DLGs) following a defined and specific nomenclature proposed originally for such a task. This particular nomenclature defines the notation of mosaics and DLGs in a synthesized and unique manner, with the advantage that it shows how to generate and design them after the parameters expressed on their own names. As a result, by means of an algorithm and some computational codes, it is possible to recreate in 3D any of those grids directly from their own names.Current nomenclature for tessellations is also analyzed, finding severe disadvantages, such as the excessive length of their notations or their non-uniqueness character. A new nomenclature is proposed in order to define and generate consistently and unequivocally n-uniform mosaics in a consistent manner with the current nomenclature used for the Archimedean (regular and semiregular) tessellations.
