This analysis is formally identical to the well-known Pushover Analysis commonly applied in seismic engineering, except for the fact that the increasing load scheme is applied downwards.
It has been shown in various works that two-dimensional models are not capable of representing the real behavior of RC frame structures, forcing the engineer to use a full 3-D model of the structure.

However, in the field of computational mechanics, the MRA has not been, in a real sense, fully utilized in the numerical solution of engineering problems either by the traditional finite element method (FEM) or by the wavelet finite element method (WFEM).
Basic Isoparametric Node Extended Shape Function An 8-node solid element is very popular in engineering practice due to its versatility and balance of computational accuracy and cost.
With advent of the element with a new MRA, the MRA will find a wide application in numerical solution of engineering problems in a real sense.

The design water head is 160m, the pier applied with large and concentrated loads requires the prestressed structures when the reinforced concrete cannot meet the engineering requirements of crack.
