In several previous studies regarding foldable structures comprised of rods and knots, it has been usual to simplify their geometry to lines and points respectively. However, this study assumes that the dimensions that these elements necessarily acquire (due to their material condition) constitute an important issue in the folding and unfolding process. To test this hypothesis, the research first defines the concept of kinetic range and its various variants and studies how variations in the radius of the rods, the eccentricity of the knots and the opening angle influence this parameter. Furthermore, this study will demonstrate that this parameter is extensible to bar bundle systems and scissors systems and finally will verify that the results obtained by using algorithm-driven models are also verifiable by mathematical methods and experimentation using physical models. As a result, the methodology followed in this article allows the inclusion of a comparative table that classifies the performance of the structural systems studied in order to establish which is the optimum in relation to their kinetic range.

The study of deployable structures has been carried out traditionally by simplifying their constituent elements—joints and rods—to ideal entities. However, in this paper the dimensional thickness of these elements is taken into account, in order to evaluate their incidence on the foldability of four deployable structure systems. We have examined the eccentricity that occurs specifically at the joints themselves. Our study ultimately characterizes the incidence of this factor by defining noteworthy parameters common to both tube bundle and scissor systems, enabling us to establish a comparison and draw relevant conclusions.

The National Capitol of Cuba was built between 1926 and 1929, with very short completion terms for the technical-construction means of that time. The historic-technological article describes its dome’s bearing structure and it analyzes the constructive method used in the central part of this urban symbol. The analysis begins from a very rigorous study of the original plans, on-site visits made at the beginning of its rehabilitation, historic photographs belonging to the Ministry of Public Works and the revision of the published texts and photographs in The Capitol Book, of which there are only two physical copies in the premises of the Havana City Historian’s Office and in the Cuban Ministry of Culture. ^{1 1} Five copies of the book are available in US University Libraries (Harvard Library, University of Florida, green Library of the Florida International University, University of Miami, University of Kansas, University of California, Riverside). The so-called Capitol Book (El Libro del Capitolio) was written by Emeterio S. Santovenia, in (1933). Its real title is: República de Cuba. Capitolio. Other recent publications about the Capitol of Havana include: Aniceto Ramos, Rolando (1998). El Capitolio de La Habana. Ed. José Martí. Vázquez García, Humberto.

The text is accompanied by several axonometries that facilitate its graphical understanding.

The public housing built under the Franco regime in Spain (1939–1975) brought about the largest urban growth in the country’s recent history. It shares similar characteristics with other public housing built in Europe during the 20th century, and today it houses a predominantly multicultural and socioeconomically precarious population. This study analyses and evaluates three estates that make up a new urban axis in the city of Murcia. The objective is to evaluate the benefits and shortcomings of these developments in order to establish rehabilitation plans, which will seek to improve the lives of their inhabitants and enhance their experience of the urban area from environmental, functional and interactive perspectives. The methodology used for this study is based on the application of three systems of indicators in order to obtain a quantitative and qualitative evaluation of each neighborhood. The quantitative analysis evaluates the urban area in terms of environmental sustainability, while the two qualitative systems explore the neighborhoods’ functionality and ability to instil a sense of attachment, and therefore responsibility, among their inhabitants. In its conclusions, the article provides concrete lines of action for updating and regenerating these residential areas that form a significant part of the city of Murcia.
