Question

a. What is the purpose of lateral ties in a column? b. In shear wall design, requirements related to shear resistance are specified in TMS 402 Section 7.3.2.6.1.1. (shown below) Explain why the "code" stipulates these requirements. When designing special reinforced masonry shear walls to resist in-plane forces in accordance with Section 9.3, the design shear strength, ¢ Vn, shall exceed the shear corresponding to the development of 1.25 times the nominal flexural strength Mn, of the element, except that the nominal shear strength, Vn, need not exceed 2.5 times required shear strength, Vụ . 7.3.2.6.1.1 c. In beam design, what is the difference between rho balance (PBAL) and rho max (PMAX)? d. What are the three main methods used to determine the compressive strength of concrete masonry, f'm. O O O e. Describe clearly (with sketches) how another type of horizontal reinforcement may be provided in the wall besides that used in Problem ONE.

Answer 1

a. lateral ties are used to support reinforcement bars on column it helps lateral bars to prevent buckling. it resists the shear force and prevent to shear failure.
