Shear-axial failureThe ties configuration in accordance with every requirement of ACI 318-14 or newer for confinement and shear strength in a reinforced concrete (RC) column is strong required so that the RC column can dissipate seismic energy through flexural mechanism. In addition, according to ...
The conservatism of one-way shear strength in some expressions of ACI 318 (14) balances the not consideration of biaxial shear design in the code. However, the use of more refined or accurate expressions as in ACI 318 (19) makes the consideration of biaxial shear for design a need. ...
Now with 318-14, start out with Chapter 5 and 6 for analysis, then go to chapter 9 for beams. Chapter 9 in turn points you Chapter 21 to get phi, Chapter 22 to get the particulars of the stress block and the shear strength of the concrete, and the shear strength of reinforcing. Th...
d. Design Example 4: ACI 318-14, section 22.9 (shear friction) Our last design example will look at using reinforcing bars for transferring earthquake-induced shear forces from a concrete wall to a concrete diaphragm as shown in Figure 6. In this exa...
Even though the spacing of shear reinforcement exceeds the spacing limit recommended by current design codes (ACI 318-14), shear strength of UHPFRC beam was noticeably greater than current design codes. Therefore, the spacing limit of 0.75d can be allowed for UHPFRC beams....
strength, which can be used to instantaneously resist large horizontal loads such as wind or seismic forces in addition to resisting gravity loads. RC shear walls must be carefully designed to provide not only adequate strength, but also sufficient ductility to avoid brittle shear failures. Several...
Bertram and Hegger (2012) also noted that the size effect on shear strength was more substantially affected by the beam height as compared with the web thickness, and that about 12–14 % higher shear capacity was obtained when the effective prestressing force increased by 20 %. By comparing ...
The strain at rupture of concrete varies as indicated by the plots in Figure 1-1, but in developing the ACI Code equations for flexure, a limiting crushing strain of 0.003 is assumed (ACI 318-14, Section 22.2.2.1). A review of the stress–strain curves for different- strength ...
equations for shear strength of RC elements included in different codes are empirical, they were initially derived on the basis of a number of experimental data with which they showed a good correlation, for example, EC- 2 [2] is based on Zsutty [3], and ACI 318-14 [4] is based on...
The ldh/db values satisfied the requirements of ACI 318-14 [1] and ACI 352-02 [11]. The applicability of ACI 318-14 provisions when high-strength bars are used is to be verified. The aim of this paper is to provide experimental evidence of the behavior of full-scale exterior beam-...
