Seismic isolation creates a protective layer between building and ground. Special devices placed between building and foundation protect all components. Increases damping rate from 5% to 20% and above. Only method controlling both floor drifts and accelerations simultaneously
Analysis settings wizard determines TBDY 2018 parameters step by step. Building risk category and seismic design category can be selected. Structural system type (concrete or steel + concrete) is defined. Ductility level can be set as high, limited or hybrid
Building consists of 8 stories with 3m height except ground story (4m). Column dimensions vary from 0.40x0.40m to 0.50x0.50m. Beam dimensions are 0.25x0.60m at all stories. Shear walls have width of 0.35m at first and second stories
Formwork scaffolding design and calculation added. Column stirrup selection and double stirrup options introduced. Improved reinforcement quantity calculations and concrete quantity display. New earthquake regulation wizard with map selection feature
Study compares TBEC-2007 and TBEC-2018 earthquake codes for 8-story steel building. Building designed as business center with 35x24m dimensions and 840m2 living area. Concentrically braced steel frames used with high ductility levels
