Nowadays, the contemporary architectural practice is asking further mutual combination between structure and architecture. But the traditional curriculum system of structural mechanics and building structure in our country has lagged behind the development of architectural practice. The contents of the courses of structure mechanics and building structure are obsolete and isolated with each other. In order to satisfy the demanding of the development of architectural practice, the curriculum system of building structure for undergraduate students major in architecture is reformed. This reformed curriculum system is composed of courses, such as building mechanics, structure lectotype and the art of building structures. The corresponding class hours, text books, teaching and assessment methodology are also renovated comprehensively. This reforming and practice of the curriculum system of building structure has greatly improved the students’ understanding of the relationship between structural performance and architectural function.
