Other methods approved by the building official. Webpremium to a Concrete Special Moment Resisting Frame(SMRF). This cost is mostly since columns in HMF systems need to be larger to accommodate the larger joint shear as well as the reduced column cross section due to the duct. If we could come up with a way to enhance the joint shear of the column by 25% +/- it could help make this system more cost
