Why EE

?Earthquake causes disaster　　　?Many engineering experiences

?Effective engineering countermeasures?Strong uncertainty

?Balance between safety and economic?What is EE

?The role of EE in earthquake disaster reduction

Contents of the course

?Engineering Seismology, earthquake action (SGM, intensity, response spectra, GM time history)

?Engineering prevention against EQ, seismic design of buildings, geotechnical prevention against EQ, lifeline system engineering prevention against EQ

?Earthquake disaster management

Risk management

?为了将不可接受的风险降到可接受的水平，管理意识到的风险的公共过程。它包括用科学和技术识别、预测和防御或减轻未来地震后果投资效益的方式。地震风险管理包括一个调整过程以确保降低不可接受的风险，为了达到这一目标，城市或地区必须提高自己的能力，达成社会、科学、技术、政治、法律和经济的一致意见以制定和实施降低社区易损性和不可接受风险的公共政策。这呼唤对减轻、预防、应急反应和恢复对策或规定的长期投资，但对减轻对策要有很高的优先权并不断提高。

Engineering Seismology

?Earthquake Intensity, Intensity Scale and Intensity rating?Strong ground motion observation and data process

?Engineering characteristics of strong ground motion and ground motion attenuation

?Effect of local site condition on ground motion and ground failure

?Seismicity, seismo-tectonics, and seismic province

?Potential source area delineation and seismic parameter determination

Seismic hazard analysis, seismic zonation and microzonation

Risk assessment

?What can happen (e.g., economic loss, death, injuries, and loss of function expected from ground shaking, ground failure, surface rupture, tsunami wave run-up)?

?What are the odds for each potential outcome happening?

?What are the likely consequences and losses for each potential outcome?

地震风险管理中的基本前提是

一元投入必须产生至少一元的效益

?In drafting a new seismic code, or revising an existing code, it is necessary to take into

account non-engineering considerations such as the cost-benefit ratio, it is necessary to balance the cost of seismic design against the reduction of future losses from earthquakes. The

estimation of future losses must recognized not only structural damage but also the economic and social impacts, which can be very severe. It must also be kept in mind that if the cost of construction is increased by 5%, then fewer structures will be built.

Engineering prevention against earthquake

?Experiences on earthquake damage of engineering structures, and main engineering countermeasures

?Engineering prevention level and design motion?Principle and requirements on seismic design of buildings

?Main analysis methods for seismic design of structures

?earthquake lab. test

?Engineering structural vibration control?Geotechnical earthquake engineering?lifeline system earthquake engineering?Strengthening & retrofitting

Earthquake disaster management

?Earthquake disaster prevention and engineering fortify

?Seismic risk assessment and management（vulnerability evaluation and damage forecasting）

?Administrative and financial instruments for earthquake disaster reduction

?Emergence counterplan for destructive EQ, technique and equipments

?Damage and loss evaluation in EQ, emergencerescureand relive,and reconstruction
