Portable Modular Classrooms & Portable Large Multipurpose Rooms, California
Structural Engineer for portable modular steel moment frame classrooms. The classrooms can be used anywhere in California which necessitated a structural design capable of resisting the maximum seismic demand forces. These high lateral loads were transmitted through C channels into HSS columns by advanced moment connections. The roof and floor of the modular units were designed as individual diaphragms. For the multipurpose buildings, some classrooms were designed with no longitudinal walls allowing up to 14 modular units to be connected at the sides forming an expansive multipurpose space. Roof top moment frame pagodas were provided at the center of the diaphragm for an aesthetic appeal of a permanent multipurpose building and to provide above roof window openings for natural day light & ventilation.
