20.5 Special Requirements in Design of Structures Subjected to Earthquake Loads 855 20.5.3 Structures in the Areas of Moderate Seismic Risk: Intermediate Moment Frames (ACI Code, Section 18.4) In regions of moderate seismic risk (SDC of C), the moment frames should be designed as intermediate moment frames. The ACI Code, Section 18.4, gives provisions for the design and detailing of intermediate moment frames as follows: 20.5.3.1 Longitudinal Reinforcement Requirements. If the compressive axial load for the < A g f c∕10, ′ the member is considered to be subjected only to bending and the following is applicable (ACI Code, Section 18.4.2.6): Positive moment strength at joint ≥ 1 negative moment strength at that face of the joint: 3 M + nl ≥ 1 3 M− nl (left joint) (20.57a) M + nr ≥ 1 3 M− nr (right joint) (20.57b) Neither the positive nor the negative moment strength at any section along the length of the member should be less than 1 the maximum moment strength provided at the face of either joint: 5 φM + n or φM − n ≥ 1 5 max (φM n at either joint) (20.58) 20.5.3.2 Transverse Reinforcement Requirements Beams. It is assumed that the plastic hinges will form at the end of the beams. According to this, the beam ends should be specially detailed to provide the beam with necessary ductility. Hoops should also be provided over a length equal to 2d (d is the effective depth of the beam) measured from the face of support toward midspan. The first hoop should be located at a distance ≤ 2 in. from the face of support. Maximum spacing of transverse reinforcement should not exceed the smallest of ⎧ d ⎪ 4 ⎪8 × (diameters of smallest longitudinalbarenclosed) S max ≤ ⎨ (20.59) ⎪24 ×(diameters of hoopbar) ⎪12 in. ⎩ When hoops are not required, stirrups should be used. Spacing of stirrups should be ≤ d/2 through the length of the member (ACI Code, Section 18.4.2.5). Columns. Transverse reinforcement of columns of intermediate moment frame should be designed with spiral reinforcement or with hoops and stirrups as follows: Spiral reinforcement should satisfy the requirements for ordinary compression member (ACI Code, Section 25.7.3): Hoops should be provided at both ends of the member over a length l 0 measured from the face of the joint, spaced a distance s 0 . (ACI Code, Section 18.4.3.3). Spacing S 0 shall not exceed the smallest of the four items listed below or ⎧8 × (diameters of smallest longitudinalbar) ⎪ ⎪24 ×(diameters of hoopbar) S max ≤ ⎨1 (20.60) ⎪ of smallest cross-section dimension of column 2 ⎪ ⎩12 inch
