Current beam appears original to house (approx 100 year age), (4) 2"x10"s, aligned vertically. Current beam has (3) staggered adjustable steel columns, placed between 8' and 10' along span. Cupping of ...

In the seismic resistant design of moment-resisting frames, the beam-column joint is regarded as a crucial point for consideration. Post–earthquake research indicates that, under high shear stress, ...

Early damage to beam‒column joints during an earthquake can cause rapid degradation of structural seismic performance or even collapse of buildings. Installing reinforced concrete (RC) wing walls to ...
