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
