Analysis and Application of Wind Exposure Categories and Ground Roughness Exponents in Wind Engineering

Wind load is a main design load for building structures. Due to rapid development of construction in China, some clauses of Building Loading Code GBJ9 87 are not suitable for engineering application. In this Paper, analysis for wind exposure categories and relative ground roughness exponents has been given on the basis of the principle of wind energy dissipation presented by the author. This study may be an important reference for revision of Building Loading Code GBJ9 87. [
