INTRODUCTION When the section of a member is under the action of an axial tension force

2、N, the section is said to be an axial tension member section. Just as the column section, when there is a moment M acting simultaneously with the axial tensile force, the section is an eccentric tension member with eccentricity e0 =M/N on the tensile side of the member. Though tensile resistance is

3、a shortcoming of concrete, there are still many members with tension used in engineering practice. Tension members may be found in the lower chord of a pre-cast truss, in one of the legs of a twin-legged column, in the wall of a vessel under internal pressure , in the tie rod of a tied arch and etc.

5、mbers is often based on serviceability limit state. The design value of tension steel reinforcement is controlled by the allowable crack width. The Chinese code stipulates that in reinforced concrete tension members, the design value of tensile reinforcement should be no more than 300Mpa. 2. STENGTH

6、 OF MEMBERS WITH AXIAL TENSION Test results on reinforced concrete members with axial tension show that the tension 3 may be taken by both concrete and reinforcement before concrete is cracked, and the tension is taken by the reinforcement alone after concrete is cracked. Fig.8.2 shows an axial tension section at the ultimate state. The equation may be written as Af N
