About this file
This is a structural calculations document prepared by BWE SL for the Los Penasquitos Gateway project located in Los Penasquitos Canyon Country Preserve in San Diego, California. The document was prepared for MW Peltz + Associates on September 10, 2024, under project number 14225A. The structural design includes six round Southern Pine columns ranging from 4 to 13 feet in length and one 21-foot beam, all with 18-inch round sections. The calculations are based on ASCE/SEI 7-22 standards and include comprehensive analysis of wind and seismic loads applicable to the San Diego County location at 226.85 feet elevation, with a design wind speed of 96 miles per hour (700-year mean recurrence interval) and seismic design category D parameters.
The structural analysis demonstrates that all members meet wood design code requirements under AWC NDS-18/SDPWS-21 ASD standards, with unity checks ranging from 0.027 to 0.096, indicating adequate capacity for the applied loads. The calculations include distributed loads from roof live loads, wind loads in two directions, and seismic forces, with load combinations evaluated according to the National Design Specification. Footing design analysis is referenced but detailed calculations are contained in supplementary handcalc documentation. The document includes RISA-3D modeling output with member properties, wood grades and species selections, and complete envelope unity checks for all structural members.

Value provided is 3-second gust wind speeds at 33 ft above ground for Exposure C Category, based on linear interpolation between contours. Wind speeds are interpolated in accordance with the 7-22 Standard. Wind speeds correspond to approximately a 7% probability of exceedance in 50 years (annual exceedance probability = 0.00143, MRI = 700 years). Values for 10-year MRI, 25-year MRI, 50-year MRI and 100-year MRI are Service Level wind speeds, all other wind speeds are Ultimate wind speeds.
Site is not in a hurricane-prone region as defined in ASCE/SEI 7-22 Section 26.2.
