Dwellings using wood-framed walls shall be braced in accordance with this section. Devise a method of adequately bracing structural masonry walls over 8 ft. Thousands of dollars of scaffolding is damaged, a forklift that was parked near the wall is totaled, pallets of material are obliterated and unusable.

Who is responsible for developing the bracing plan?

The testing program established bracing procedures that can be used in the field by qualified personnel. Figure 1 shows a cantilevered wall with two base doweling conditions that influence the ability of a wall to perform as internally braced. This wall will develop cantilevered capacity as the grout cures and then the wall performs with base fixity and moment continuity. Bar joists or beams bearing on, or connected to, the wall may not qualify as ‘final lateral support’. Wall framing shall be continuous from the lowest floor to the wall top plate at the roof. All edges of sheathing shall be supported on and fastened to blocking or framing. Braced wall panels may not be required on the balloon-frame wall portion provided the bracing amount and brace spacing requirement are satisfied for the building side.

Fractions of panels shall be rounded to the nearest one-half braced wall panel. Perpendicular sides to the left and right sides are the front and rear sides. The resulting value shall be 2 or greater, to be consistent with subd. Where joists are perpendicular to braced wall lines above or below, blocking shall be provided between the joists at braced wall panel locations to permit fastening of wall plates in accordance with the fastener table in the ch.

Braced wall panels shall be permitted to be supported on cantilevered floor joists meeting the cantilever limits of s. Masonry walls shall be constructed in accordance with the requirements of this section. All previously used masonry units shall be free from physical defects which interfere with the installation or impair the structural properties of the unit. Masonry walls must be braced while they are under construction to provide safety to construction workers and other persons that may occupy the space adjacent to those walls.

What is striking is the absence of external bracing on both projects. So, from a practical point of view, it is impossible to prevent walls under construction from blowing down under some circumstances. What are the limitations of some of the anchor types?

Will the masonry wall construction be conducted during periods of cold weather?

Will the project involve the use of high-speed scaffolding?

Will the project involve the use of high lift grouting? Just like mortar, grout must hydrate, and until such time adds no bonding strength to the wall system. Will the wall incorporate reinforcement rods within the masonry unit cavities?

Are knee braces being proposed in the bracing system plan?

If knee braces are used, lateral braces should also be used. When will the mason install the required initial period bracing?

How long should a bracing system be kept in place?

How can one detect if the bracing system connection and attachment points work loose?

Who is responsible for developing the bracing plan?

Who is supplying your bracing system materials?

Will the crane operator be able to see the entire panel lifting and placement process?

What type of anchors will be used to connect the brace to the deadman?

What type of deadman is being planned?

How long will you keep the bracing system in place?

How will you detect if the bracing system connection and attachment points work loose?

Is the contractor aware of this standard?

What type of bracing is being planned?

What kind of brace anchor is being planned?

Are movement joints greater than 25 feet planned?

If yes, will there be more than two braces per panel? Is the contractor planning to use high lift grouting methods?

If knee braces are used, will there be lateral braces? If no, obtain a detailed explanation of the contractor’s proposed bracing method that will be used. Will the crane be located inside or outside of the building?

If wood or cable bracing is used, is the bracing being provided on both sides of the wall? If steel pipe bracing is used, is it capable of resisting wind loads on both sides of the wall? Straight coil loop inserts allow braces to be attached to the reinforcement of an ungrouted wall. Workers are now protected from the overturning and collapse of walls even before grout is poured. This braced attachment imparts added strength to the wall to resist the forces of wind. All three test walls were subjected to a minimum 35 mph simulated wind force. A fourth test was performed on a minimum grouted 16 ft. Air bag pressure measured using piezometers. Brace is connected at approximately 8 ft. Brace is connected at approximately16 ft. Brace is connected at approximately 16 ft. The fourth test on a free standing, minimum grouted wall also withstood a wind force in excess of 60 mph – demonstrating the strength that is rapidly achieved in a reinforced, 16 ft.

There was noticeable deflection and cracking as loading was applied. However, walls returned to a nearly plumb condition after loading was removed. Many of the walls observed during testing showed some amount of joint cracking. It is reasonable to assume when using the information in this report that walls in excess of 24 ft. Metal tilt braces are attached from base connection to wall at a max. Metal brace connected to wall via minimum ¾ x 4 inch diameter straight coil loop insert looped around rebar. Braced wall panels shall be located at each end of a braced wall line. Braced wall lines with a length of 16 feet (4877 mm) or less shall have not less than two braced wall panels of any length or one braced wall panel equal to 48 inches (1219 mm) or more.

Only braced wall panels parallel to the braced wall line shall contribute toward the required length of bracing of that braced wall line. Linear interpolation shall be permitted. Where a braced wall line has parallel braced wall lines on one or both sides of differing dimensions, the average dimension shall be permitted to be used for braced wall line spacing.

The total adjustment factor is the product of all applicable adjustment factors. The adjustment factor is permitted to be 1.0 when determining bracing amounts for intermediate braced wall lines provided the bracing amounts on adjacent braced wall lines are based on a spacing and number that neglects the intermediate braced wall line.

Where the braced wall line length is greater than 50 feet, braced wall lines shall be permitted to be divided into shorter segments having lengths of 50 feet or less, and the amount of bracing within each segment shall be in accordance with this table.

The total length of bracing required for a given wall line is the product of all applicable adjustment factors. The length-to-width ratio for the floor/roof diaphragm shall not exceed 3:1. Applies to stone or masonry veneer exceeding the first story height. The adjustment factor for stone or masonry veneer shall be applied to all exterior braced wall lines and all braced wall lines on the interior of the building, backing or perpendicular to and laterally supported veneered walls.

Applies to panels next to garage door opening where supporting gable end wall or roof load only. Mixing intermittent bracing methods from braced wall line to braced wall line within a story shall be permitted. Blocking shall not be required over openings in continuously sheathed braced wall lines. Blocking at horizontal joints shall not be required in wall segments that are not counted as braced wall panels.
