OPTIMAL URBAN FORMS OF LINEAR CITIES INCLUDING HIERARCHICAL SPATIAL STRUCTURE WITH CONSIDERATION OF FLOOR HEIGHT

Spatial Structure Changes in Mohtasham Urban Area of Kashan

  Today, Mohtasham urban area in Kashan does not benefit from a suitable condition and has lost its importance over the last decades. The vast majority of the local inhabitants of this historical area have left their homes and have been replaced by weak and underprivileged dwellers of the urban community. Moreover, historical buildings have been demolished or worn out structurally, and local m...

Investigating the Spatial Organization and Structure of Iranian Cities till Mid Qajar Era and Presenting Pattern of Traditional Structure of Cities in This Era

Optimal transportation and the structure of cities

Following the recent analysis of Lucas and Rossi-Hansberg [10], we study the equilibrium structure of cities. By adopting a different (monetary) specification of commuting costs, we are able to prove the existence of equilibrium in more general situations: non-circular cities, or multi-sectorial production. The main mathematical tool in this paper is the use of optimal transportation theory. Th...

The spatial structure of Latin American cities.

"Using published census data, metropolitan area population and employment statistics are constructed for several large Latin American cities in 1950, 1960, and 1970, and compared to similar statistics from selected North American cities. The Latin cities are experiencing decentralization of population and some decentralization of employment. Overall population density patterns of large Latin ci...

MULTI-OBJECTIVE OPTIMAL DESIGN OF SATMD INCLUDING SOIL-STRUCTURE INTERACTION USING NSGA-II

In this paper, a procedure has been introduced to the multi-objective optimal design of semi-active tuned mass dampers (SATMDs) with variable stiffness for nonlinear structures considering soil-structure interaction under multiple earthquakes. Three bi-objective optimization problems have been defined by considering the mean of maximum inter-story drift as safety criterion of structural compone...
