Explore stairs drawing method 2 within the CSI ETABS framework for the structural analysis of a 15-story building with basement.

Draw the slab with the contour option, using wawel slab type one, then switch to type two, adjust rib spacing, and assign the slab across selected stories.

Mesh slabs and walls in ETABS with finite element method, creating square shell elements and a 0.5 size. Align slab and wall masses through shell assignments and mesh settings.

this lecture teaches modeling base supports and foundations in etabs, assigning joint restraints as pin or fixed, and considering soil capacity to verify foundation conditions for a multi-story building.

Define gravity loads on slabs and assign uniform shell loads to each story in ETABS. Verify the posted loads for each story match the specified live load values.

Learn how to apply gravity loads on beams by assigning distributed and machinery-related loads in ETABS, modeling beam nodes and shell nodes for a 15-story plus basement structure.

Define earthquake static loads for a regular building by applying X and Y seismic loads with UBC 97 and computing base shear from site zone and soil profile.

Define dynamic earthquake loads for a regular building by switching from static to a response spectrum dynamic load in the X direction. Compare results with static and run the analysis.

Define wind loads for a 15-story structure in Lebanon by converting 33 m/s to mph and applying VK multipliers based on plan dimensions L1 and L2.

Define diaphragms in ETABS to model earthquake loads, representing slabs per story and assigning a unique diaphragm to each of 16 stories to reduce lateral analysis degrees of freedom.

Define the mass source for earthquake analysis by selecting only the dead load, unchecking other options, and specifying the load to be included under seismic assessment.

Define modal cases to capture earthquake and wind effects by modeling x and y directions and rotational modes, setting three modes per story, e.g., 48 for a 16-story building.

Define stiffness modifiers for each element in the ETABS model. Set columns' frame torsion-related inertia to 0.7 on both axes, beams to 0.35, slabs to 0.25, and walls to 0.5.

Select the entire structure, run analysis, and perform a database check with a tolerance of about 50 to verify the model, ensuring no warning messages.

Define load combinations before running calculations by selecting default design combinations from the database; the project does not automatically define them for concrete frame design.

Run the ETABS analysis to compare center of mass with center of rigidity, compute the percentage difference from x and y coordinates using the Excel sheet, and review results.

Compare dynamic and static earthquake loads in a 15-story plus basement structure, scale dynamic loads in X and Y directions to match static demands, and verify with reactions.

Evaluate story displacement under lateral loads for a 15-story plus basement building, ensuring dynamic and static analyses stay within the allowable limit, around 86–98 mm.

Check story drift analyzes inter-story displacement and global drift limits using ETABS, calculating delta and verifying X and Y drifts stay under 2 percent with a 1.716 s period.

Learn how to design columns in a concrete frame using ETABS: define column sections, run analysis, select stories, and perform complete frame design while checking rebar area and safety.

Design and verify a shear wall by applying uniform reinforcing, selecting bar sizes and spacing, and checking flexural and shear requirements for safe earthquake resistance.
