Grade Transition at Walls in Precast Concrete Parking Structures

It is almost inevitable that precast parking structures at some point encounter a change in grade between the exterior and interior of the structure. Grade changes are not limited to sites with variable topography, but they also occur on relatively level sites as the interior vehicular ramp(s) begin their ascent from the ground floor to […]

Electric Vehicle Loads in Precast Concrete Parking Structures

Precast concrete parking structures have been designed for the IBC-prescribed minimum live load of 40 psf with the introduction of IBC 2000, and this provision is still contained in IBC 2021 and ASCE 7-22. Both these codes prescribe the 40 psf uniform live load with a nonconcurrent 3.0 K concentrated load applied over a 4½” […]

Planning For Future Expansion Of Precast Parking Structures

Baseball legend Yogi Berra once opined that “It’s tough to make predictions, especially about the future”. Perhaps he was unconsciously channeling the Nobel Prize winning Danish physicist, Niels Bohr (1885-1962), who earlier noted that “Prediction is very difficult, especially if it’s about the future.” Or perhaps Yogi was simply being his own colorful self. While […]

Parking Efficiency in Parking Structures

There are several factors that influence the cost of parking structures beyond the obvious costs of labor and material that contribute to the total cost. One example is the geographic location of the construction site and the premium costs associated with union scale erection vs. open shop. Another example is the level of attention given […]
