This Excel sheet can be used to analyse lateral forces on shear walls under the combined impact of earthquakes and wind. It enables the user to input seismic analysis parameters, wind information, and building dimensions to determine resulting shear forces, moments, and load distribution among walls, facilitating structural stability design.
Why Combined Wind and Earthquake Analysis Matters
Shear walls are the primary lateral load-resisting elements in most low-to-mid-rise reinforced concrete and masonry buildings. They must be designed to resist both wind and seismic forces, and codes such as ACI 318 and ASCE 7 require engineers to consider both independently and in combination with gravity loads as part of the governing load combinations.
In regions of moderate to high seismicity, seismic forces typically govern. In low-seismic regions or for taller structures, wind forces may be more critical. This sheet allows engineers to assess both conditions rapidly in a single file.
