摘要

A self-bracing, two-way moment frame precast system for industrial support structure and method of erecting a precast industrial support structure without temporary or permanent bracing or shoring are disclosed. This is accomplished by utilizing a moment frame element in two directions to create free standing tower that requires no bracing during erection or in service. The system also utilizes a connection that allows the erection crane to achieve alignment during erection such that the entire system can be erected by a ground based personnel.
