Volume change is a challenging aspect of reinforced concrete and post-tensioned construction. If no measures are taken to minimize restraint to shortening from columns, braced frames, moment frames, and shear walls, strains resulting from concrete shrinkage, creep, temperature, and elastic shortening associated with post-tensioning can result in high tensile stresses and significant cracking. In an elevated slab, the common solution is to use a pour strip. An innovative pour strip design based on the use of mechanical couplers is discussed.

The conversion of a historic brewery in Bavaria, Germany, into an office and events space posed a challenge: the need to replace five large stone window frames while retaining the original aesthetic of the façade. Using computer-aided design files specifying the geometry of the window frames, digital patterns were created to print polymer formwork elements that were successfully used to cast the window frame elements.

A unique feature of the Port of Seattle’s expanded International Arrivals Facility main terminal building at the Seattle-Tacoma International Airport is the incorporation of 37 precast concrete shear walls along the west side of the structure. These walls are exposed to view, so a quality finish was essential. All walls were cast horizontally, with formed surfaces on one long side and the two radiused ends. The other long side was manually completed with a hard-troweled finish.

When builders began construction of renowned Spanish architect Antoni Gaudí’s Temple of the Sagrada Família in 1882, the primary construction material was sandstone. As construction continues, concrete—high-strength concrete in particular—has become a critical construction material for the cathedral in the last two decades. Support columns have high-strength reinforced concrete cores and exterior stone or precast concrete “drums” that serve as permanent formwork.

This month’s Q&A discusses moisture vapor protection for concrete slabs that will be covered with moisture sensitive flooring materials. It focuses on the water vapor movement through a concrete slab, potential ways of reducing the water vapor transmission rate, and means of selecting a viable moisture vapor mitigation option.
