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
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).
Benjamin G. Almeda was a Filipino inventor known for his contributions to the development of appropriate technologies in the Philippines. He is credited with inventing the Almeda Cottage Industry (ACI) Technology, which aimed to empower rural communities by providing them with tools and equipment for small-scale production. Almeda's work focused on creating sustainable solutions for local industries, agriculture, and livelihoods, ultimately helping to improve the quality of life for many Filipinos.

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.
