Foundation Anchorage

"Foundation Anchorage" Details and Base Shear Capacity for Log Buildings

Nowadays, log structures serve both residential and commercial occupants as an alternative to conventional light-frame wood structures simply because they may be much more sophisticated in style, "Foundation Anchorage" than before. They are constructed using round logs stacked a single by 1 vertically and interlocked with corners. Lag screw and thru-rods are also utilized for load path continuity.

..."Foundation Anchorage" is an important element in the seismic overall performance of each log structure and light-frame ones. Obviously, lag constructing require different anchorage on account of their developing mass. So, proper "Foundation Anchorage" ought to not be lightly taken.

Exterior Beam-Column Joints

When it comes to beam-column jointing for the "Foundation Anchorage", hooked bar anchors are broadly utilized for longitudinal beam flexural reinforcing bars. It is also advised that hook bars really should bent in to the joint using the hook embedded as far as possible from the vital area. Although hook bar anchors are used for beam-column connections, headed bars could be employed to ease this congestion dilemma inside the beam-column joint that's brought on by steel congestion in an exterior or corner beam-column joint.

The fabrication of headed bars is carried out by attaching a forged head, or anchor plate, for the reinforcing bars to present a mechanical anchorage by head bearing. Lately, according to study and check, extension for the ACI 352R-0210 was produced to include several layers of diameter bars with closely-spaced heads. The cause for such addition was because beam-column joist with larger diameter bars and little head ratio connect the members better.

Eccentric beams are generally employed at edge or corner from the constructing frame, but they have a tendency to have lower joint shear strength than related concentric connections. When the adding slabs and transverse beam framing into to a join, it can reduce the effect of eccentric beams on edge beam-column-slab connections. It should be noted that in earthquake-type loading, corner beam and column joint are more vulnerable to deterioration than edge or interior joints. This can be for the truth that lack of slabs and beams confined on two opposite faces...
