Working Stress Design Method is a traditional method used for designing steel structures.

• It is based on the concept of allowable stress.

• The stress in the structure is limited to a certain percentage of the yield stress of the material.

• The design is done by assuming a certain load and then checking if the stresses are within the allowable limits.

• This method is not commonly used nowadays as it does not take into account the actual behavior of the structure under load.

• Examples o...read more
