The ACI codebook puts an upward limit on the spacing between ties. ACI Code 7.10.5: Vertical spacing of ties shall not exceed 16 longitudinal bar diameters, 48 tie bar or wire diameters, or least dimension of the compression member. If the ties are spaced too far apart, the column will experience shearfailure and barrel in between the ties. [4]
The tie in a cavity wall [1] [2] is a component used to tie the internal and external walls (or leaves)—constructed of bricks or cement blocks—together, making the two parts to act as a homogeneous unit. It is placed in the cavity wall during construction and spans the cavity. The ends of the tie are designed to lock into the mortar. Also ...
EN 1996-1-2 deals with the design of masonry structures for the accidental situation of fire exposure, and is intended to be used in conjunction with EN 1996-1-1, EN 1996-2, 1996-3 and EN 1991-1-2. This part only identifies differences from, or supplements to, normal temperature design and it deals only with passive methods of fire protection.
Components on a concrete masonry unit and brick cavity wall. A cavity wall is composed of two masonry walls separated by an air space. The outer wall is made of brick and faces the outside of the building structure. [6] The inner wall may be constructed of masonry units such as concrete block, structural clay, brick or reinforced concrete. [6]
Because the masonry veneer is non-structural, it must be tied back to the building structure to prevent movement under wind and earthquake loads. Brick ties are used for this purpose, and may take the form of corrugated metal straps nailed or screwed to the structural framing, or as wire extensions to horizontal joint reinforcement in a fully masonry veneer or cavity wall.
Coursed masonry construction arranges units in regular courses. Oppositely, coursed rubble masonry construction uses random uncut units, infilled with mortar or smaller stones. [1] If a course is the horizontal arrangement, then a wythe is a continuous vertical section of masonry [2] one unit in thickness. A wythe may be independent of, or ...
Control joints must have adequate depth and not exceed maximum spacing for them to be effective. Typical specifications for a four-inch-thick slab are: [8] 25% depth of material; spacing at 24 × to 36 × of slab depth (some specification call for a maximum of 30 ×) special care for inside corners
