Location-specific basic wind speeds shall be permitted to be determined using www.atcouncil.org/windspeed. Structures that require special consideration of their response characteristics and environment that are not addressed by this code or ASCE 7 and for which other regulations provide seismic criteria, such as vehicular bridges, electrical transmission towers, hydraulic structures, buried utility lines and their appurtenances and nuclear reactors. Basic design wind speeds, miles per hour (mph) (km/hr) determined from. In others, city staff conduct design review, or a community group conducts design review and makes recommendations to developers or city staff. These maps differ from the other maps because the wind speed contours include the topographic effects of the varying terrain features (Figure 4). Denvers building codes are critical in helping the city reduce greenhouse gas emissions and raise the bar on the long-term performance of all buildings in Denver. In some design review districts, an appointed board conducts design review using adopted design standards and guidelines.

The primary objective was to better understand their physical configurations, how they were used and their relative degrees of success. See ASCE 7-16for important details not included here. This separation was between thunderstorm and non-thunderstorm events. For roof tiles with nails or screws (with or without a tail clip), the axis of rotation shall be taken as the head of the tile for direct deck application or as the top edge of the batten for battened applications. Design standards and guidelines, and associated design review processes, may be recommended in asmall area plan.

Archived Denver Building Code Amendments are available for download below. This code cycle, the city placed a significant focus on energy and climate action. Moment arm, feet (mm) from the axis of rotation to the point of uplift on the roof tile. For mechanical parking structures without slab or deck that are used for storing passenger vehicles only, 2,250 pounds (10 kN) per wheel. Presentation from February 2022.

One method applies specifically to a low-sloped roof (less than 7 degrees) (Figure 5) and the second method applies to any roof slope where solar panels are installed parallel to the roof. the ASCE 7 peak-gust map speci-es a 38 m/s~85 mph! Consequently, wind speeds generally decrease across the country, except along the hurricane coastline from Texas to North Carolina. Equation 12.8-2 of ASCE 7 is used to determine the seismic response coefficient, C. This factor is even smaller for the considerable areas where the actual peak-gust wind speed is larger than 3631.2 543 m/s ~96 mph!.
