Project 1_Comparative study of different storey buildings for Seismic forces

OBJECTIVE OF CHALLANGE

1. Know how to extract different seisic responce for the structure
2. how to easily alter certain properties in ETABS model
3. know the factor influencing the dynamic charecterstucs of building
4. know the factor influencing time period of building
5. know the factor influencing mode shape of building

PROCEDURE

EFFECT OF STIFFNESS ON TIME PERIOD,EFFECT OF MASS ON TIME PERIOD,EFFECT OF MASS ON TIME PERIOD,,EFFECT OF COLUMN OREINTATION ON TIME PERIOD ,EFFECT OF FLEXYRAL STIFFNESS OF STRUCTURAL ELEMNTS ON MODES SHAPE,Effect of axial stiffness of vertocle member on mode shaape,EFFECT OF DEGREE FIXITY AT COLUMN BASE ON MDE

ALL THESE GIVE HAVE TO CALCULATE

MODEL A

MODEL B FLOORS COLUMN SIZE 400*400)

MODEL (C)

MODEL (C)

COLUMN SIZE 300*500)ORIENTATION X-DIRECTION

MODEL (D)

COLUMN SIZE 300*500)ORIENTATION Y-DIRECTION

MODEL (F)

MODEL (G)

MODEL (H)

MODEL (I)

MODEL j:10% INCRESE OF LOAD

MODEL k

: 20% INCRESE OF LOAD

RESULT:as per given quetion calculated the factor influencing the dynamic charecterstrics of a building

factor influencing natural period of building, factor influencing mode shape of oscillation
