Strut forces

The paper discusses the development of a numerical method for a multibraced excavation to estimate strut forces. Two different software were used in the proposed method. Equivalent strut forces were calculated by plane strain analysis on Plaxis 2D.

Tài liệu tham khảo giáo trình nhôm trong thiết kế xây dựng bằng tiếng anh - Chương 9 Tension and compression members 9.1 GENERAL APPROACH 9.1.1 Modes of failure This chapter covers the static design of members subjected to axial force either in tension (‘ties’) or in compression (‘struts’). The basic requirement is that the factored resistance should not be less than the tensile or compressive force (action-effect) arising in the member under factored loading.

This chapter reviews various ways of damping large space trusses. The first part discusses the use of active struts consisting of a piezoelectric actuator collocated with a force sensor. The guaranteed stability properties of the integral force feedback are reviewed and the practical significance of the modal fraction of strain energy is stressed. The second part explains the concept of active tendon
