Compute temporary shoring loads for collapsed-building search and rescue.
Force per support F = W/(n·sinθ) (W weight, n supports, θ angle); horizontal thrust = F·cosθ; total support force = F·n; safety factor K = allowable/F, K≥3 safe.
用於地震倒塌建築救援中的臨時支撐受力計算,根據結構重量、支撐角度與數量計算單根軸力、水平推力與穩定安全係數,輔助支撐方案設計。
