Loads considered in steel structure design. Computation of dead, live, snow and static equivalent wind load according to TS498. Computation of static equivalent earthquake load according to DBYBHY. Calculation of total dead load, reduced live load in a typical interior column, equivalent wind and earthquake loads of a six-story steel office building. Calculation of loads, preparation of computer model, conduction of the required analyses, control of the analysis results and, in the end, selection of required cross sections of the structural members of a six story office building composed of frames with high ductility in one direction and of frames with high ductility eccentric braces in the other direction. Modeling, analysis and design of a single story steel industrial building composed of frames with normal ductility in one direction, and of normal ductility concentric braces in the other direction.
