Introduction to Earthquake Loading in Structures CIVL3811 Engineering Design and Construction School of Civil Engineering | Faculty of Engineering THE UNIVERSITY OF SYDNEY Mode shapes of a free vibration three-storey frame (Kolousek,1973)  Characteristic deformation: (a) shear; (b) full-height bending of the framework as a whole; (c) full-height bending of the individual columns (Zalka,2001) Modal analysis which is used to calculate the natural frequencies and mode shapes of a structure. Different mode extraction methods are available. Harmonic analysis which is used to determine the response of a structure to harmonically time-varying loads. Transient dynamic analysis which is used to determine the response of a structure to arbitrarily time-varying loads. Spectrum analysis that is performed as an extension of the modal analysis, and used to calculate stresses and strains due to a response spectrum or random vibrations. Seismic Load -AS1170.4 – 2007 Site hazard factor Site sub-soil class Annual probability 1:500 Annual probability 1:1000 Estimate or calculate period Seismic -Natural Periods Seismic Load Calculate the base shear Shear Wall Shear Wall Reinforcement Shear Wall Reinforcement Shear Wall Reinforcement Shear Wall https://www.structuralguide.com/shear-walls/ Bracing System http://farasp.com/%D9%85%D9%87%D8%A7%D8%B1%D8%A8%D9%86%D8%AF- %D8%A7%D8%B3%DA%A9%D9%84%D8%AA-%D9%81%D9%84%D8%B2%DB%8C- %D8%A8%D8%A7%D8%AF%D8%A8%D9%86%D8%AF- %D8%A7%D8%B3%DA%A9%D9%84%D8%AA-%D9%81%D9%84%D8%B2%DB%8C/ https://takhribsaze.ir/%D8%A8%D8%A7%D8%AF%D8%A8%D9%86%D8%AF- %DA%86%DB%8C%D8%B3%D8%AA%D8%9F/  http://moghavemsaze.ir/%D9%BE%D8%A7%DB%8C%DA%AF%D8%A7%D9%87- %D8%AF%D8%A7%D9%86%D8%B4/%D8%B1%D9%88%D8%B4%D9%87%D8%A7%DB%8C- %D9%85%D9%82%D8%A7%D9%88%D9%85- %D8%B3%D8%A7%D8%B2%DB%8C/%D9%85%D9%82%D8%A7%D9%88%D9%85- %D8%B3%D8%A7%D8%B2%DB%8C-%D8%A8%D8%A7- %D8%A8%D8%A7%D8%AF%D8%A8%D9%86%D8%AF/ https://sakhtemanonline.com/blog/divergent-brace-2/ https://www.markazeahan.com/what-is-xbracing/ post seismic building examples https://www.irna.ir/news/82728451/%D8%B2%D9%84%D8%B2%D9%84%D9%87- %D9%87%D8%A7%DB%8C%DB%8C-%D9%83%D9%87-%D8%A7%DB%8C%D8%B1%D8%A7%D9%86- %D8%B1%D8%A7-%D8%B9%D8%B2%D8%A7%D8%AF%D8%A7%D8%B1-%D9%83%D8%B1%D8%AF post seismic building examples https://fa.shafaqna.com/news/488634/ post seismic building examples https://www.rokna.net/%D8%A8%D8%AE%D8%B4-%D8%AD%D9%88%D8%A7%D8%AF%D8%AB-23/694640- %D8%B2%D9%84%D8%B2%D9%84%D9%87-%D8%AA%D8%A8%D8%B1%DB%8C%D8%B2-%D8%B1%D8%A7- %D8%A8%D8%A7%D8%B1-%D9%84%D8%B1%D8%B2%D8%A7%D9%86%D8%AF%D9%87- %D8%A7%D8%B3%D8%AA  post seismic building examples http://zanjan-nezam.org/fa/news/detail1310/%D9%86%D9%82%D8%B4- %D9%85%D8%B1%D8%AF%D9%85-%D9%88- %D9%85%D8%B3%D8%A6%D9%88%D9%84%DB%8C%D9%86-%D8%AF%D8%B1- %DA%A9%D8%A7%D9%87%D8%B4-%D8%AA%D9%84%D9%81%D8%A7%D8%AA- %D9%86%D8%A7%D8%B4%DB%8C-%D8%A7%D8%B2- %D8%B2%D9%84%D8%B2%D9%84%D9%87/ post seismic building examples http://www.iiees.ac.ir/fa/%D8%B2%D9%85%DB%8C%D9%86%E2%80%8C%D9%84%D8%B1%D 8%B2%D9%87-31-%D8%AE%D8%B1%D8%AF%D8%A7%D8%AF-1369-20- %DA%98%D9%88%D8%A6%D9%86-1990- %D8%B1%D9%88%D8%AF%D8%A8%D8%A7%D8%B1- %D9%85%D9%86%D8%AC%DB%8C%D9%84/ post seismic building examples https://www.tehrantimes.com/news/422253/Fairly-powerful-quake-shakes-western-Iran References Apostolos Konstantinidis “Earthquake Resistant Buildings Volume A “, Alta Grafico A.E.2015.
