I have been tasked with designing a 12m span single carriageway highway bridge deck. The deck construction details have been left entirely down to me and being more form an environmental background i am very uncertain as where to look or how to go about the design, other than knowing it must be...
Thanks, i thought it was along those lines.
Regarding the lever arm depth, i seem to have found something that suggests it is because of two reasons;
1. As this is very close to the suface of the beam, steel is likely to fail as it will have very high strain
2. Concrete is weaker here due to...
Hi, Just a few questions:
1. For a singly reinforced concrete beam, why is a minimum percentage area (100As/bh) of tensile reinforcement required?
2. Why is the maximum value of the lever arm (la = z/d) limited to 0.95?
Thanks.
