Abstract：Based on the research of at home and abroad, tentative framework on performance-based wind-resistant design theory is proposed in this paper. Four kinds of wind pressure fortification levels (weak wind-pressure, middle wind-pressure, strong wind-pressure and super-strong wind-pressure) are proposed. Human body’s vibration comfort is suggested to be divided into six kinds of vibration ranks (without vibration sense, mild vibration sense, middling vibration sense, annoyance, super annoyance and unable tolerance) and three kinds of vibration levels (vibration level correlate with human’s general life, with human’s general work and with human’s physical health). Four states of structural performance level (performance health, performance sub-health, performance ill-health and performance loss) was divided according to performance demands of different buildings and human body’s vibration comfort and five ranks of structural performance objective (A, B, C, D and E) are proposed. General principles of structural wind-resistant conceptual design and calculation are suggested and basic matters of safety evaluation and socioeconomic evaluation are advised.
