The American Concrete Institute (ACI) recommends that the effective width of a T-beam be determined based on the width of the flange and the depth of the web. For a T-beam, the effective width is typically taken as the width of the flange plus a portion of the web, which can be calculated using specific formulas depending on the loading and support conditions. Generally, the effective width is considered to extend from the edge of the flange to a distance equal to the effective depth (d) of the beam on either side of the web. It's essential to refer to the latest ACI guidelines for precise calculations and considerations.
as per ACI , the ratio between column & beam concrete grades dont exceed 1.4
you can generally use 180 degree hooks, to provide enough anchorage in slabs with no edge beams. use the Ldh formula (12.5.2) of ACI 318-11
Concrete with a compressive strength of 3500 psi is typically classified as a Grade 25 concrete, according to the American Concrete Institute (ACI) standards. This strength is commonly used for residential applications, such as driveways, sidewalks, and foundations. It provides a good balance of strength and workability for various construction projects.
It can depend on the governing agency standards mostly, but the typical design life used by ACI (American Concrete Institute) is an average of 75 years. The normal range given in between 50-100 years.
A class A splice is defined in ACI 318 Section 12.15. There are two types of splice (A and B) which define the length of the splice as a multiple of the tensile development length (ld) Class A denotes a splice that has 1.0 x ld of overlap. A class B splice has 1.3 x ld. Class B is required except where splices are kept out of critical ares (see the code).
as per ACI , the ratio between column & beam concrete grades dont exceed 1.4

to prevent the beam from failing immediately when a crack occurs. If the ultimate resisting moment is less than the crcking moment the beam wold fail, but by putting a minimum percentage of steel i the concrete this can be avoided.
