Key elements should be capable of sustaining an accidental design action of A d applied in horizontal and vertical directions (in one direction at a time) to the member and any attached components; The recommended value of A d for building structures is 34 kN/m² Resolving horizontally: 25cos10 −40cos80 −15cos45 = 7.068 Resolving vertically: 40sin80 −15sin45 −25sin10 = 24.445 Therefore the resultant has magnitude √ 7.0682+24.445 = 25.45 = 25 (2 s.f.) acting at an angle of tan−1. 24.445 7.068 = 73.87 = 74 (2 s.f.) above the positive x-axis. Notes 1. You have a right triangle with the hypothenuse as your force of 32 lbs. The gravity/ (vertical component) would be sin 30 degrees x 32. The horizontal component will be cos 30 degrees x 32. = (sqrt...

Building structure seismic force shall be designed as per NBCC 4.1.8.11, with the weight of nonstructural components (Process, HVAC equipment and Bridge Crane etc) considered as effective seismic weight for base shear calculation and base shear distribution along vertical direction. A wagon is being pulled by a 300-pound force that makes a 30° angle with the ground. What are the horizontal and vertical components of the force vector? The horizontal is 150 pounds, and the vertical is 260 pounds. The horizontal is 260 pounds, and the vertical is 150 pounds. The horizontal is 346 pounds, and the vertical is 600 pounds.
