1.1 INTRODUCTION TO PLASTIC ANALYSIS AND LIMIT STATE DESIGN
PLASTIC ANALYSIS: ANALYSIS OF STEEL STRUCTURES β METHODS β
ELASTIC, PLASTIC AND DYNAMIC ANALYSIS AND ADVANCED METHOD OF
ANALYSIS BASED ON IS:800 β 2007 β IDEALIZED STRESS VS STRAIN
CURVE FOR STRUCTURAL STEEL β REQUIREMENTS AND
ASSUMPTIONS OF PLASTIC METHOD OF ANALYSIS β FORMATION OF
PLASTIC HINGES IN FLEXURAL MEMBERS β PLASTIC MOMENT OF
RESISTANCE AND PLASTIC MODULUS OF SECTIONS β SHAPE FACTORS
OF RECTANGULAR / CIRCULAR / I /T – SECTIONS β COLLAPSE LOAD
β DETERMINATION OF COLLAPSE LOADS FOR CANTILEVER , SIMPLY
SUPPORTED AND FIXED BEAMS BY ANY (STATICALLY OR KINEMATICAL
METHODβ PROBLEMS.
LIMIT STATE DESIGN : ADVANTAGES OF LIMIT STATE DESIGN OF STEEL
STRUCTURES β BASIS FOR DESIGN β CLASSIFICATION OF LIMIT
STATES β CHARACTERISTIC AND DESIGN ACTIONS β ULTIMATE AND
DESIGN STRENGTHS – PARTIAL SAFETY FACTORS FOR LOADS AND
MATERIALS β DESIGN REQUIREMENTS β STRENGTH REQUIREMENTS :
STABILITY , FATIGUE AND PLASTIC COLLAPSE β SERVICE ABILITY
REQUIREMENTS : DEFLECTION LIMITS, VIBRATION , DURABILITY AND
FIRE RESISTANCE βGEOMETRICAL PROPERTIES OF GROSS AND
EFFECTIVE CROSS SECTIONS β CLASSIFICATION OF CROSS SECTIONS
AS PER IS:800-2007
