Is more joint reinforcement needed?

An adjustable hook & eye horizontal joint wire reinforcement will be used in an exterior cavity wall system consisting of a 12-inch concrete unit masonry backup, 2-inch rigid insulation, 1-inch air space, and 4-inch concrete unit masonry veneer. This reinforcing will be installed at 16 inches on center. Since the veneer is 4-inch ground face concrete unit masonry and not face brick, is it necessary to install an additional 4-inch joint reinforcement within this wythe as well? More

Designed Versus Actual Position of Reinforcing Steel

When engineers perform structural calculations on reinforced masonry walls, they assume precise placement of reinforcing steel. In actual construction, the reinforcing steel is often not so precisely placed. How far off can reinforcement be placed? More

Misaligned dowels

On a project that I am working on, the dowels in the concrete foundation do not line up with the center of the block cells. Should I cut off the dowels and set new dowels into epoxy or can I use the existing dowels? If I can use them, should I position a reinforcing bar next to the dowel and wire them together, which in some cases may be at one side of the cell? Or should I just allow the dowel to extend along one edge of the cell and position the bar in the center of the cell? More

Reinforcing an in-place wall

An intermediate floor was removed from a warehouse. The walls were constructed with 6-inch unreinforced concrete block. No modifications were made to the wall when the floor was removed. I need to perform emergency repairs to stabilize the wall. To make the repairs quickly, I plan to bolt deep steel beams at 12 feet on center along the inside of the warehouse walls. To provide fire protection for the steel, I plan to form and cast concrete around the steel beams later. Can I use concrete block as permanent forms for the concrete or grout? Or will the grout or concrete rupture the block with "wet pressure?" More
