Background/Objectives:After recent achievements in the field of Tensegrity structure, many Tensegrity models have been investigated and evaluated. Tensegrity models have been used as symbolic or covering vast area such as fuller’s dome and other stuffs. These usages do not have sufficient attention to synthesis of architectural and structural space together.Methods/Statistical analysis: The method of this article, based on simulation and modeling of a sample structure by analyzing flow of internal forces, is adaptive methode. Restriction of exited structures to a hammock and then analysis its force flow, and consequently classify it to tensile and compressive members is the base of manner. By gathering information about Tensegrity structures and their behavior according to several definition of structural engineers and also architects, we commence combination of facts based on adaptation of existed structures with Tensegrity rules. Then, by finding a Tensegrity model and creating a replica of hammock Tensegrity, it shows the ability of structure specially in term of statistic. This outcomes can help us to develop new system of form - finding models.Findings: This system can make us able to develop modeling of Tensegrity. In the recent years, form - finding method almost base on symmetric models to expand as cover structure for vast spans. By this manner, we can design asymmetric models consist of synthesis of structural and architectural space.Application/Improvements: Form - Finding method can be developed in order to increase quality of building in term of weight of structure, flexibility, decreasing proportion of used material to its resistance and so on. In addition, we can produce asymmetric models which contain architectural space into Tensegrity structure.

A place can be considered as sustainable place that meets current needs of human and considers their needs in future. Spatial dynamicity is also one of the indices of a sustainable space, which defined the relationship of space with variable needs of human. Spatial dynamicity is an index, through which space matches itself by changes in human life over the time. In other words, special dynamicity is a quality of a space, through which space is matched with changed needs of humans through changing itself. Therefore, in regard with space dynamicity and place stability, human needs are prior to other needs. This is because; in fact meeting the needs causes more social participation of people and increase in their social interactions. However, at the current world and after expansion of modernism approach, increase in attention to vehicles and their presence has decreased direct consideration of variable needs of human and their presence in space. Hence, it could be mentioned that today, presence of vehicles in space has created a big challenge for dynamicity of space. Meeting such challenge is important, since a human-oriented dynamic space can increase human interactions and can also promote place sustainability and make using space possible over the time. This study adopts a qualitative-analytical approach to find factors that can form a sustainable space through strengthening the dynamics of space and increasing level of social interactions. Findings indicate that in regard with creating any kind of change in space, in addition to consider future, past of the place should be also considered. This study has found that human scale in an important factor in this framework and considering future. Moreover, in regard with past and emphasizing effect of place on human, historical memory of space should be considered and with emphasizing effect of human on place, collective memory factor should be considered. Accordingly, through assessment of each factor, a series of strategies should be achieved based on future and a series of expected results should be achieved based on past, so that framework of a change can be specified in limit of space dynamics index.

Sustainable development covers different environmental, social and economic dimensions. In this paper, we discuss social aspects of sustainability emphasize that a local community center should include security and sociability concepts. Therefore, the objective of the paper is finding suitable design principles that could increase these two concepts. The methodology of the article is survey and case study. The selected site is CHIZAR local community in Tehran. The paper will conclude that some design principles such as diversity in function, visibility, Attractive Street frontages and stay area increase security and sociability concepts.
