How to design singly reinforced beam with limit state method

The Limit State Method is revised version of the ultimate load method. This method considers the shortcomings of ultimate load theory. LSM focuses on the ?acceptable limit? prior to failure as contrary to the ULT which provides the load factor on failure load of the structure.

In the method of design founded on LSM, the structure is designed to securely resist all loads likely to operate on it during its life as well as meet the serviceability requirements. The tolerable limit for the safety and serviceability requirements prior to failure takes place, is known as limit state. A structure is supposed to attain its limit state or failure conditions, if the structure all together or in part turns to be unsuitable for one reason or another, throughout its anticipated life. Limit State Design refers to a philosophy of design where one designs a structure so as to it will not extent any of the identified limit states for failures throughout the projected life of a structure. Usually, the structure is designed based on the most crucial limit state and shall be examined for other limit states.
