ETABS Advanced Course Modeling&Design of19 stories Buildings

Learn to start a new etabs project, create a 19-story model from the new model form, explore template options, set metric units and aci 318-19, and save the project.

Define the mass source in ETABS by selecting specified load patterns to combine self-weight and loads; set dead and s-d multipliers to 1, add live load 0.25, uncheck vertical mass.

Explore automatic meshing in ETABS by dividing slabs and walls into small rectangles with auto mesh options, setting maximum mesh size, and viewing shell and frame meshes.

Define eight pier labels and assign them to four shear walls in ETABS, so walls act like columns, carrying normal forces and moments across all stories.

Assign frame sections in ETABS by defining master and similar stories, then apply RC column and wall sections across stories, keeping core thickness consistent.

Explain the P-Delta effect in high-rise modeling, linking axial load P, lateral forces and displacement Delta to overturning moments, with ACI code checks (theta < 0.1, Cd=4) in ETABS.

Evaluate whether to include the P-Delta effect in ETABS by checking theta values via an Excel sheet, then demonstrate enabling P-Delta options and running analysis for all load patterns.

Explores plan and vertical irregularities, explains soft story and heavy story criteria, and demonstrates stiffness and mass checks in ETABS and Excel to assess regularity.

Master evaluating story drift, drift ratio, and total displacement in a 19-story Etabs model using ubc guidelines, scaling ultimate results by 0.7, and verifying results against allowable values.

Learn how modal analysis in etabs models dynamic seismic response, define modal cases, ensure 90% modal participating mass ratio, and prepare for response spectrum and time history analyses.

Define the response spectrum in ETABS using UBC 97 with CA 0.24 and CV 0.32, apply 5% damping, and configure Spec X/Y load cases and dynamic load combinations.
