The reasons to limit lateral deflection are: - To avoid damage problem in building associated with shear racking and bending deflection. - To avoid uncomfortable horizontal movement of the occupants

3.5 Space Structures of Columns and Frames Buildings conceived as columnar space structures by considering a simple rectangular space-form enclosed by four slender columns

3.1 Building Systems 3.2 The Hierarchy of Structural Action 3.3 Building Forms Conceived as Solid Structures 3.4 Building Forms Conceived as Space Structures

2.2 Estimating Overall Forces -Vertical dead loads(5～10kN/m²) -Vertical live loads = equivalent dead loads(2～5kN/m²) - Horizontal wind load - Horizontal earthquake load 2.3 Aspect Ratios and Overturn Resistance Aspect ratio (h/d) is one of the main considerations in schematic level. It is very important for overall stability of a building against overturning. 2.4 Strength and Stiffness of Buildings Carrying capacity –enough strength (against loads) Rigidity of building – enough stiffness (against deformation) 2.5 Symmetry and Asymmetry in Building Forms Asymmetry building is caused by: - asymmetry of building elevation - asymmetry of supporting system - asymmetry of dead loads or live loads

2.1 The Assumption of Integrity
