Assignment 1 Date of assignment: 18 January 2006 E-course on Seismic Design of Tanks
What is expected? • Part I: Reading assignments are to be completed as soon as possible • Best if you finish the reading assignments on the same day • It will help you appreciate the next lecture E-Course on Seismic Design of Tanks / January 2006
What is expected? • Parts II and III • To be completed by 19 January; before we send out the solutions of these to you. • Please do not send the solutions to us. • Compare your answers with the solutions we will send. • Feel free to go back and review the lecture while answering the questions. • Some questions may not have very specific answers • This is in line with our engineering profession wherein certain questions have no specific answers.

Part II: True / False • Identify the following statements as True or False 1.1)Hydrodynamic pressure varies linearly with liquid height. 1.2)Impulsive mass is less than convective mass for short tanks. 1.3)Net hydrodynamic force on the container wall is zero. 1.4)Hydrodynamic pressure on base causes overturning moment on tank. 1.5)Convective mass acts at lower height than impulsive mass. 1.6)With the inclusion of base pressure effect, overturning moment on tank reduces. 1.7)Impulsive and convective masses depend only on height of liquid.
