Replacement I-beam

I was asked to look into the replacement of a current I-beam in a house located in Beverly Hills. This I-beam supports a bearing wall of the 2^nd floor. Due to a center post removal, this I-beam would not be sufficient in strength to support the total length of the second floor wall and its carrying weight.

Calculations has been executed for its flexural design and deflection caused by the dead and live loads and their combinations. The calculated initial serviceability criteria cannot be exceeded for the replacement beam. A ´GOOD´ sign has been implemented in the calculation to give a head up if the calculation is equal or better than the initial serviceability criteria requirements. Meaning the new I-beam is strong enough to function according the previous I-beam standards.
