AI Technical Summary
Because of the age of age, wooden pillars in old masonry structures are prone to serious damage such as rot, stress cracking or insect damage. The existing technology is difficult to effectively improve its earthquake resistance during transformation, resulting in insufficient structural toughness and easy collapse.
The newly added reinforced concrete frame is used to reinforce the masonry structure wooden columns, including the two sides of the log columns being wrapped with new reinforced concrete window frames and door frames. U-shaped pull-knot steel bars, stirrups and longitudinal steel bars are used for connection and casting to form a higher strength structure.
The overall seismic resistance of the original structure is improved, so that the new and old structures share the seismic effect, enhance the resilience of the house, prevent the structure from collapse, and at the same time, the construction is simple and has good economic and environmental benefits.
