CE6015 TALL BUILDINGS L T P C 3 0 0 3
OBJECTIVES:
The design aspects and analysis methodologies of tall buildings will be introduced. The stability analysis of tall buildings is another important objective of this course.UNIT I DESIGN CRITERIA AND MATERIALS (9)
Development of High Rise Structures - General Planning Considerations - Design philosophies - Materials used for Construction - High Strength Concrete - High Performance Concrete - Self Compacting Concrete - Glass - High Strength Steel
UNIT II LOADING (9)
Gravity Loading - Dead Load - Live Load - Live load reduction technique - Impact Load - Construction Load - Sequential Loading. Lateral Loading - Wind load - Earthquake Load. Combination of Loads.
UNIT III BEHAVIOUR OF VARIOUS STRUCTURAL SYSTEMS (9)
Factors affecting growth, Height and Structural form. High rise behaviour of Various structural systems - Rigid frames, braced frames, Infilled frames, shear walls, coupled shear walls, wall-frames, tubular structures, cores, outrigger - braced and hybrid mega systems.
UNIT IV ANALYSIS AND DESIGN (9)
Modeling for approximate analysis, Accurate analysis and reduction techniques, Analysis of buildings as total structural system considering overall integrity and major subsystem interaction, Analysis for member forces, drift and twist, computerised general three dimensional analysis.
UNIT V STABILITY OF TALL BUILDINGS (9)
Overall buckling analysis of frames, wall-frames, Approximate methods, second order effects of gravity of loading, P-Delta analysis, simultaneous first-order and P-Delta analysis, Translational,
Torsional instability, out of plumb effects, stiffness of member in stability, effect of foundation rotation.
TOTAL: 45 PERIODS
OUTCOMES:
At the end of this course the student should have an understanding on the behaviour of tall buildings subjected to lateral building. The students should have knowledge about the rudimentary principles of designing tall buildings as per the existing codes.
