EQE 685 – Seismic Analysis and Design of Tall Buildings

INSTRUCTOR : Prof. Dr. M.Nuray Aydınoğlu

 

COURSE OBJECTIVES : The objective of the course is to provide a background for the theoretical and practical aspects of performance-based seismic design of tall buildings.

 

• Tall buildings: Definition and significance of tall buildings in seismic design
• Recent history of development of tall building seismic design guidelines
• Structural systems and elements of tall buildings

Structural systems commonly applied in tall buildings
Structural elements: Their behaviour and role in seismic response
Basic guidelines for establishing tall building structural systems

• Performance-based design essentials of tall buildings

Seismic performance objectives

• Structural modeling for tall buildings: Nonlinear modeling options

Lumped plasticity: Plastic hinge model
Distributed plasticity: Fibre (cell) model
Modeling of beams, slabs, columns, walls, coupled walls and others

• Analysis for preliminary design

Capacity design applications: Deformation-controlled and force-controlled response
Pushover analysis as a preliminary design tool (Aydınoğlu 2014)
Preliminary proportioning procedure for coupled walls (Vuran & Aydınoğlu 2016)

• Nonlinear Response History Analysis (NRHA) in time domain

Selection and scaling of seismic ground motion
 P-Delta effects

• Performance Evaluation Criteria

Deformation-controlled evaluation criteria in terms of plastic rotations and/or strains
Force-controlled evaluation criteria: Critical and non-critical response quantities

• Three-stage performance-based design of tall buildings according to recent Turkish Building Seismic Code - TBSC 2016

Other seismic design codes and guidelines for tall buildings

• Case studies on seismic modeling, preliminary design and performance evaluation of actual tall buildings
• Tall building foundation design including soil-pile-structure interaction in adverse soil conditions.
