ABSTRACT

It is quite apparent that combined bending of the base plate and shear lug caused by design moment in column will alter the lever arm used for anchor bolt tension calculation. This in turn will affect the net tension carried by the anchor bolts. With the current requirements for ductile detailing of anchor bolts, specifically for columns that are part of seismic load resisting system in seismic design categoryDor above, any reduction in anchor bolt tension will benefit the design engineer and reduce construction cost.
