[amp_mcq option1=”Only (i)” option2=”Only (ii)” option3=”Both (i) and (iv)” option4=”Both (ii) and (iii)” correct=”option3″]<\/p>\n
The correct answer is: C. Both (i) and (iv)<\/strong><\/p>\n The main reinforcement in a front counterfort in a counterfort retaining wall is provided on the bottom face near the counterfort and the top face near the center of the span.<\/p>\n The bottom face near the counterfort is subjected to a large bending moment due to the weight of the soil and the water pressure. The top face near the center of the span is subjected to a large tensile force due to the bending moment.<\/p>\n The main reinforcement is provided to resist these forces.<\/p>\n The reinforcement on the bottom face near the counterfort is typically in the form of a continuous bar or a series of bars that are tied together. The reinforcement on the top face near the center of the span is typically in the form of a single bar or a series of bars that are tied together.<\/p>\n The reinforcement is designed to provide a safe and economical structure.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Only (i)” option2=”Only (ii)” option3=”Both (i) and (iv)” option4=”Both (ii) and (iii)” correct=”option3″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[641],"tags":[],"class_list":["post-5914","post","type-post","status-publish","format-standard","hentry","category-concrete-technology-and-design-of-concrete-structures","no-featured-image-padding"],"yoast_head":"\n
