STRUCTURAL REQUIREMENTS of LCSs Restraint (sufficient members and supports to provide for equilibrium) Strength (sufficient material to prevent rupture) Rigidity (sufficient resistance to deformation) Ductility (sufficient capacity for energy absorption)
COMPATIBILITY REQUIREMENTS of LCSs Spatial layout (e.g. hotels, bearing walls) Materials (e.g. masonry and vaults) Services (integration of services) Construction (e.g. bearing walls, integral forms, tower cranes)
STRUCTURAL BEHAVIOR Displacements/deformations Load Internal force Load Internal forces Energy storage Language of description is mechanical.
UNDERSTANDING BEHAVIOR of LCSs Modeling of LCS Prediction of loads Analysis of mechanical forms Understanding in terms of basic modes
DIRECTION of PREDOMINANT LOAD Vertical (gravitation) Horizontal (wind) Combination (earthquake)
GEOMETRIC FORM 3D forms - solid, systems of 1D and 2D forms Dimensionality 1D forms - rod, planar curve, spatial curve 2D forms - plane, surface, systems of 1D forms Orientability
MECHANICAL FORM Combination of geometric form and load Orientation Load Geometric Form Mechanical form = Oriented and loaded geometric form
MECHANICAL FORMS (BEAM and COLUMN) Geometric Form = ROD Load Orientation Load Orientation BEAMCOLUMN
MECHANICAL FORMS (ARCH and CURVED BEAM) Geometric Form = PLANAR CURVE Load ARCH LoadOrientation Load Orientation CURVED BEAM
UNDERSTANDING SPECIFIC BUILDING LCS’s Resolve hierarchy of structural problems Determine scale of problem (overall building, breakdown of main structure, detail elements) Resolve structure of elements Recognize the MF of elements
