Structural Modelling using Etabs 2018

1) AIM & INTRODUCTION: Conceptualize a 7 storey building in seismic zone 5 and design it using ETABS

PROCEDURE:

Data required to ETABS analysis:

• pinned supoort ,Base + 9 story (ground to terrace) + 1 mumty
• Column 450mm x 600mm,Beam 400 x 500mm , shear wall 300 thick
• Live load 2.5 kn/m^2 ,floor finish -1.5 kn/m^2,wall load 5kn/m , water tank 20k litre over mumty equivalent to 200kn overall load

CONCEPTUAL DESIGN CONSIDERATIONS BEFORE ANALYSIS:

• re-entrant and cutout check & modification(compromise)
• vertical irregularity(soft story)
• planar irregularity(looks symmetrical)
• 2% shear wall area with respect to building area(8m^2)
• stiffness modifier for column beam & shear wall(.35 for beam,0.7 for oyhers)

key point to remember while modeling

• no slab,no wall in ground level
• proper end releases in beams as per engineer intend
• no interior wall load in terrace
• comparsion of static and dynamic forces and revising the facctor

RESULT:

Conceptualized a 7 storey building in seismic zone 5 and designed it using ETABS succesfully
