The tension failure loads predicted by the CCD method fits experimental results over a wide range of embedment depth (e.g. 100 – 600 mm). [2] Anchor load bearing capacity provided by ACI 349 does not consider size effect, thus an underestimated value for the load-carrying capacity is obtained for large embedment depths.
For this reasons, the size effect on the strength in brittle failures of concrete structures and structural laminates has long been ignored. Then, however, the failure probability, which is required to be < 10 − 6 {\displaystyle <10^{-6}} , and actually does have such values for normal-size structures, may become for very large structures as ...
This is a list of structural failures and collapses of buildings and other structures including bridges, dams, and radio masts/towers. This is a dynamic list and may never be able to satisfy particular standards for completeness.

The test is carried out using a metal mould in the shape of a conical frustum known as a slump cone or Abrams cone, that is open at both ends and has attached handles.The tool typically has an internal diameter of 100 millimetres (3.9 in) at the top and of 200 millimetres (7.9 in) at the bottom with a height of 305 millimetres (12.0 in).The cone is placed on a hard non-absorbent surface.

Water was seeping under the dam, [4] which also bowed more than 36 feet (11 m) under the pressure of the water it was holding, and the concrete started cracking. The bowing was alleviated by using dynamite to blast a 13-foot (4.0 m) space for the excess water to spill over. The cracking was claimed to be normal because of the drying concrete.
In 1994, Jeff Bezos co-founded the future e-commerce behemoth Amazon in a Seattle garage. In an interview with Time magazine, the Amazon CEO revealed he gave himself a 30 percent chance that ...
