Which of the following theory is the most accurate method to design arch?

Which of the following theory is the most accurate method to design arch? Correct Answer The trial load method

Thin cylinder theory can only be relied upon for rough estimation of dimensions of the arches. The Elastic theory does not take into account the thickness of arch rings and the restrictions at the abutments. The Trial load method removes the above objections and leads to an accurate estimation of the stresses in arches.

Consider the following statements in respect of arched construction made of voussoirs: 1. The superimposed load is transferred to the sidewalls only by the strength of cohesion of the mortar between the voussoirs. 2. The arch may fail under crushing when the compressive stress or thrust in it exceeds the safe crushing strength of the voussoir material. 3. Every element in the arch is subjected to compression only. 4. Failure of the arch due to the sliding of any voussoir past the adjacent one due to transverse shear can be avoided by reducing the height of the voussoirs. Which of the above statements are correct?
