The document summarizes a project seminar on analyzing the seismic behavior of multi-story reinforced concrete flat slab structures with varying plan aspect ratios and slenderness ratios. It outlines the objectives to analyze structures using response spectrum analysis and determine safe design limits. It describes the modeling assumptions for 11-story structures and defines 25 structural models that vary the plan aspect ratio from 1 to 5 and slenderness ratio from 0.41 to 2.88. The methodology involves reviewing literature, modeling in ETABS, comparing results, and drawing conclusions.
