The Effect of Spatial Location of Supporting Facilities (Central Library and Student Center) to Modify Properties of Spatial Structure of Univ ersities Applied Study in Iraqi Universities


AbstractSpatial Location of buildings and facilities (especially supporting facilities - centrallibrary and students centers) is one of many other problems that emerged in architecturaland urban studies, which focused on the functional and symbolic importance of the locationand how it can changes spatial morphology of the campus. Previous studies clarifieddescriptively: the relationship between components of the university, the possibility of spatialintegration of the university buildings during the future expansion processes, relationshipbetween buildings and their impact on the movement through its spaces. The objective aimof this research is to identify the relationship between spatial location of supporting facilitiesand how it can modifying and changing properties of spatial structure of universities.Forachieving this goal required the following steps:1. Modeling a comprehensive theoretical structure that describes this relationship2. Analyzing six of Iraqi universities by using the program of geographic informationsystems G.I.S. Three types of spatial location have been choice (at the center (A) ,atboundary (B), multiple locations(C). Research suppose that spatial location of supporting facilities affects to change and modifyproperties of spatial structure of universities.Results can clarified following statements:1- localydegree of local control: the highest values were concentrated in type A then C andfinally at B.the upper limits are concentrated in the main axes leading to the supportspaces. Legibilitydegree of connectivity: The highest values were concentrated in type A and B and thenC and the upper limits are concentrated in the main movement axes.Globally1- global Integration: The highest values were concentrated in the type A followed by Cand B and the upper limits are concentrated in the main axes of all design patterns2- Degree of global choice: The minimum values were concentrated in universities withtype C and this refers to spaces with high permeability that stand out in the main axessurrounding the supporting facilities , followed by universities with the B and A3- legibility: The results indicated convergence in the degrees of legibility and emerged thehighest values in type A followed by B and then C and legibility increase in the main axes.4- centrality: results showed the existence of a compatibility of values of the three modesof design, although the difference of spatial locationresearch conclusions are:1 - The mismatch of the geographical centrality with the functional centrality and this cometo be achieved through the use of spatial system of movement which work on theinterconnections of the university buildings and characterized by high functional centrality2 - Match the values of legibility with the spatial location , where legibility increase intype A followed by the B then C3 - the lack of correspondence between the spatial location of the support spaces and thespread of movement
