==>>SWAY AND NON-SWAY OF STRUCTURE==>>

SWAY AND NON-SWAY OF STRUCTURE==>>

NON-SWAY==>> If structure in stable in any condition then it is non sway condition of structure...

CONDITION FOR NON-SWAY=>

For non - sway structure have same moment of inertia through all members ...loads applied is centric for all members (it may be UDL or may be point load)... Supports are at same level..




                                                                              [1ST]                                  [2ND]

1ST structure ==>> NON-SWAY

2ND structure ==>> SWAY


SWAY==>> If structure is not in stable position ..and structure tilled , then it is called sway of structure..

CONDITION FOR SWAY==>>

=> IF moment of inertia of all members are different then sway come into action ...structure tilled in that side where moment of inertia is less...

=> IF applied load is not in center than sway also come in action.. at which side load is less at that side sway will come..

=>IF supports of structure are not in same level than sway also come in structure...

=>IF all condition are applying in single structure than we consider all condition at same time...
