Currently, building codes do not specifically provide load combinations for design of underground structures. This should be addressed by code bodies because it is becoming a more pressing issue as the modern urbanization trend continues. Although ASCE/SEI 7-16, Section 2.3.5, allows the design professional to develop load combinations for a specific project, designers typically do not have the expertise, time, or budget to develop the factors. This article presents a set of recommended load combinations as a temporary solution until load combinations can be calibrated and supported by research.
