Instruction - How to use EDES_B flow


STEP1 Introduction

STEP2 Selection of Method

STEP3 Detail of selected method



 STEP1 Introduction

EDES_B flow guides you to find out appropriate methods for earthquake damage estimation. The right side of the first page shows the list of methodologies in the three categories; 1: Earthquake Source, 2: Propagation and Amplification, and 3: Building Response and Damage. The left side is the flow chart showing the result of your selection.



Furthermore, the methodologies in each category are divided into three or four levels depending on their difficulty or difference of necessary information.

Category 1: Earthquake Source

E-1: Hypocenter and Magnitude
Methodology to determine earthquake source characteristics based on hypocenter and magnitude,
E-2: Grade 1 + fault plane
Methodology to determine earthquake source characteristics based on E-1(hypocenter and magnitude) and fault plane,
E-3: Rupture process
Methodology to determine earthquake source characteristics based on rapture process in a fault plane.

               

Category 2: Propagation and Amplification

P-1: Epi-/Hypo-central Distance
Attenuation formula based on epi-/hypo-central distance and Magnitude,
P-2: Minimum Distance to Fault Plane
Attenuation formula based on minimum distance to fault plane
P-3:

Equivalent Hypo-central Distance to Fault Plane
Attenuation formula based on equivalent hypo-central distance to fault plane

Category 3: Building Response and Damage

B-1:

Intensity
Methodology to determine building response and damage based on seismic intensity.
B-2:

PGA, PGV
Methodology to determine building response and damage based on PGA (peak ground acceleration) or PGV (peak ground velocity) of earthquake ground motion.
B-3:

Response Spectra
Methodology to determine building response and damage based on response spectra of earthquake ground motion.
B-4:

Wave Form
Methodology to determine building response and damage based on wave form of earthquake ground motion.

Category 4: Others

Methodologies related to other hazards such as tsunami, landslide, etc.

STEP2 Selection of Method

By clicking the boxes in the left side, you can see the result of your selection and the rest of your choice. For example, by selecting “E-1” method in the first category, you will get the following figure:






Also, by selecting “P-2” method in the second category, you will get the following figure:







By selecting “B-2” method in the third category, you will get the following figure:







If the message “more” appears in the second category, it implies that there are more methods to be selected. Therefore, by clicking the message “more”, you will get a new figure as follows:






At the end, by selecting “P2-2-1” method in the second category, you will get the final figure for your selection.

STEP3 Detail of selected method

To look for the detail explanation of each method, please click the title in the right side of the window. Then, a new window will appear which describes the brief explanation about the method and related URLs in which you can get more detail information. For example, by clicking the title “E-1” in the first category “Earthquake Source”, you will get the following window:








Then, by selecting the URL at the bottom (“Grade-1” in the above example), you will reach at the following web-site which provides more detail information, related URLs and references, etc.:








In case of the second category “Propagation and Amplification”, for example, by clicking the title “P-2-2-1”, you will get the following window with a list of attenuation formulas, software and calculator on WEB.








By clicking one of the formulas, you will get the detail explanation of that formula. “Software” enables you to execute attenuation formulas using an Excel macro file. Also, by clicking the title of attenuation formulas in “Calculator on WEB”, you can demonstrate results of the attenuation formula on the map as shown below:








In case of the third category “Building Response and Damage”, for example, by clicking the title “B-2”, you will get the following window with software names:








Then, by clicking the “GESI_Program”, you will reach the web site where you can download the software.
