Before revision: Arching or Compressive Membrane Action (CMA) in Reinforced Concrete Slabs Introduction Arching or compressive membrane action (CMA) in reinforced concrete slabs occurs as a result of the great difference between the tensile and compressive strength of concrete.
After revision: Arching or Compressive Membrane Action (CMA) in Reinforced Concrete Slabs Idealisation of arching action forces in laterally restrained slab Arching or compressive membrane action (CMA) in reinforced concrete slabs occurs as a result of the great difference between the tensile and compressive strength of concrete.
