Allowable Stress Design Specification and AISC-99 LRFD Specification. ASDIP STEEL is an engineering software that performs the structural design of steel members and connections such as composite non-composite beams steel columns base plates anchoring to concrete shear connections and moment connections. When dead load is larger as compared to live load then LRFD becomes economical. Then take that load and design it with LRFD assuming it is all dead load.
