Abstract:

ACI 332 requires contraction joints in plain and reinforced concrete slabs-on-ground. For post-tensioned (PT) residential slabs-on- ground, PTI DC10.1 permits contraction joints to minimize and conceal random cracks. The layout of contraction joints in residential slabs requires special considerations, which are discussed in this TechNote.

Abstract:

During construction, the load on the slabs can be up to 2 to 3 times their self-weight, which can damage serviceability and structural safety of the slabs with early-age concrete. In the present study, an existing model to predict the load on slabs during construction was modified to account for the use of regular supports and temporary supports in the shoring system, considering construction step where temporary supports are removed. Additionally, the effective supporting area of the shore was introduced to account for the uneven distribution of shores, thereby improving the prediction of construction loads on slabs. To verify the accuracy of the modified model, loads on shores were measured at a wall-type residential building under construction in South Korea. For 2 stories, the loads on shores were measured and the measurement lasted for 45 days. The comparison between predicted and measured slab construction loads showed that the predicted construction load agreed with the measured construction load.

Abstract:

While it might seem that hydrodemolition is only appropriate for big projects, it can also be an economical choice for compact applications, such as the renovation of a residential garage floor. The floor had heavy damage that required recasting with new concrete. The floor was diamond ground, so the hydrodemolition method was well-suited to create a rough, consistent bonding surface for the new concrete.

Abstract:

Concrete aggregates produced in two regions in North America have been identified as the cause of deterioration to tens of thousands of residential and light commercial concrete foundations. The article provides an overview of the deterioration mechanism, manifestations of the reaction in North America, current state of knowledge for identification and quantification, and current and proposed legislation.

Abstract:

An assembly system of vertical construction is used for the construction of a 16-story mixed-use residential development in Detroit’s Greektown district. The technology allows workers to assemble floor plates; façade elements; and selected mechanical, electrical, and plumbing systems at ground level. One-by one, the assemblies are raised and locked into their final positions through connections with the building’s two reinforced concrete cores.
