dear
what is u r qualification if ur a civil engineer this is a
stupid question.
see there is difference in working stress method and limit
state method
eg. if we design any member of building in case of working
stress method ie eg FOR 1000KN THERE IS DESIGN FOR ONLY
THIS LOAD
BUT in case of limit state method a factor of safety 1.5 is
used ie same member in limit state will be designed FOR
1.5 X 1000 = 1500KN
THUS THERE IS SAFETY IN DESIGN UR MEMBER CAN WITHSTAND LOAD
OF 1000KN BUT WE DESIGN IT TO WITHSTAND A LOAD 1500KN IE U
R STRUCTURE WILL NOT FAIL.
IF U DESIGN STRUCTURE FOR 1000KN LOAD AND ITS LOAD
CARRYING CAPACITY IS 1000KN THEN U R STRUCTURE WILL
COLLAPSE
THUS LIMITE STATE METHEOD IF BEST TODAY
IN 1900 WORKING STREE METHOD CAME
AFTER THAT ULTIMATE LOAD METHOD CAME
& THEN CAME LIMIT STATE METHOD
