Double layer Lattice Domes (DLLDs) are one of the most popular light weight structures selected for covering special area such as sports centers and exhibition halls. These structures are generally regarded to be safe when dealt with earthquakes. Space truss complexes consist of thousands of members and joints that make them highly redundant and stiff structures. These factors usually lead designers to ignore the dynamic analysis, especially in the preliminary design stages. The main aim of this work is to present a simple pattern for the assessment of the distribution of equivalent horizontal static earthquake loading for DLLDs to allow the designers to bypass the complexities of early stage dynamic analyses. The seismic behavior of DLLDs under twelve famous earthquake accelerograms is also presented.
