Derivation of formulas in Appendix H of GB 50341-2014

The derivation process of the formulas in Appendix H of GB 50341-2014 mainly involves the calculation of seismic design parameters for building structures, specifically including the structural self-weight, live loads, seismic forces, and wind loads. Due to space constraints, it is not possible to list them all; below are the derivation processes for some of the commonly used formulas: 1. Formula for calculating the self-weight of a structure: Self-weight of structure = Self-weight due to concentrated loads + Self-weight due to distributed loads. Self-weight due to concentrated loads = Total weight of concentrated loads. Self-weight due to distributed loads = Total area covered by distributed loads × Mass per unit area. 2. Formula for calculating live loads: Live loads = Total weight of live loads. Total weight of live loads = (Unit live load coefficient × Floor area) + (Unit live load coefficient × Floor area) + ... 3. Formula for calculating seismic forces: Seismic forces = Basic seismic shear force × Magnitude influence factor × Design neglect magnitude influence factor × Seismic intensity influence factor. Basic seismic shear force = Dynamic elastic reaction coefficient × Total mass of the structure × Design acceleration. 4. Formula for calculating wind loads: Wind loads = Wind pressure × Area. Wind pressure = Wind speed exponent × Air density × Wind resistance coefficient × Surface roughness coefficient × Combined displacement coefficient. The above are only the derivation processes for a small portion of the formulas in Appendix H; for detailed derivation processes, it is necessary to refer to the standard document directly. It is recommended that you consult the full text of GB 50341-2014 or seek advice from a professional engineer for more detailed information. .
