4 Pre Design Checklists for 20 Story Buildings in ETABS– Part 1 Damage Limitation or drift Eurocode

Welcome to Part 1 of this essential series for structural engineers working on tall buildings. Before you design a single beam or column of a 20‑story apartment building, four critical checklists must be completed after analysis in CSI ETABS. This episode focuses on Damage Limitation according to Eurocode 8 (EN 1998‑1). Damage Limitation is a Serviceability Limit State (SLS) verification that ensures your building remains operational and its non‑structural elements (partitions, cladding, glazing, MEP systems) are not damaged after a frequent, moderate earthquake. Ignoring this check can lead to massive repair costs, legal disputes, and loss of occupancy – even if the structure does not collapse. 📌 What you will learn in this video ✅ The difference between No‑Collapse (ULS) and Damage Limitation (SLS) under Eurocode 8 ✅ How to set up the correct lower‑level seismic action with q = 1 in ETABS ✅ How to extract elastic inter‑storey drifts from your ETABS model ✅ How to apply the drift limit formula from EC8 clause 4.4.3.2 ✅ A practical, step‑by‑step demonstration on a real 20‑story apartment building 📚 Full Series Overview This is Part 1 of a 4‑part series. The remaining checklists will be released weekly: 1. Damage Limitation** (SLS drifts) ✅ Today 2 . Irregularity Check – Plan & Elevation 3. Building Classification & Behaviour Factor `q` 4. P‑Delta Effect (Second Order Analysis) 🔔 Subscribe and click the bell so you don’t miss the next critical checklist. ❓ Have questions? Drop them in the comments section.
