Abstract. This study aimed to develop a model to accurately predict the acceleration of structural systems duringan earthquake. The acceleration and applied force of a structure were measured at current time step and the velocityand displacement were estimated through linear integration.

Keywords: complex terrain; typhoon wind field; CF simulation; surface roughness length; topography

1. Introduction

!ormally" strong winds have #een associated with two types of wind in typhoon prone region.

The first one is the nature wind and the other one is the typhoon" or say severe tropical cyclone.

$any investigations a#out the vi#ration and #uckling %static sta#ility& characteristics of frames of

various types have #een carried out. Cheng %'())& have studied the elastic critical loads for plane

frames #y using the transfer matrix method. general digital computer method has #een descri#ed

#y Cheng and +u %'()'&

2. Section title: Level 1

The system examined" shown schematically in Fig. ) is a #eam of varia#le cross section"carrying a so called heavy tip massM.,ts mass moment of inertia with respect to the perpendicular

axis at the centroidSis denoted #yJS. The pu#lications %#olghasemi and -alali '((" /ounesian

and 0smail1adeh '()(" rvin and 2akhtiari3!e4ad '())& are considered also with rotating #eams

in which nonlinear oscillations are investigated. nalytical and experimental investigations on

vi#rating frames carrying concentrated masses with characteristics of frames have #een studied #y

5. Conclusions

numerical simulation procedure for predicting directional typhoon wind fields over complexterrain has #een proposed in this study.

The reduction of natural frequency depends on the crack depth and crack location.

9igher drops in the in3plane natural frequency are o#served when the crack is located near the

roots or corners of the frames
