Extremely hard and brittle materials are difficult to machine in conventional process.
The wire materials of: Brass, zinc coated brass, copper coated brass, Tungsten and molybdenum.
The Figure 3(a) shows the relationship between the wet and Dry-WEDM, 3(b) represents the machining of different materials.
Fig.4 (a) SEM micrograph of wet WEDM, (b) Wet-WEDM of surface roughness (Ra=1.45µm, I=23A, V=40V, (c) Dry-WEDM of surface roughness(Ra=1.51µm, I=14A,V=20V) (Source: Abdul kareem, Journal of applied sciences 2011) They investigated the low speed (LS-WEDM) machining in gas atmosphere condition, it reveals the better straightness, shorter gap distance and excellent finish cutting [28].
Future Work The WEDM is one of the non-contact machining technique and most preferable process, which is used for the machining of conventional materials to nascent materials [31].

Five half-scale of exterior beam-column joints studied in this experimental research simulated existing buildings in South Korea, which contains little or no transverse reinforcement in beam-column joint regions, wide range of beam longitudinal reinforcement ratio and low material strength.
Materials and test specimens To consider the low strength of concrete and steel re-bars used in the existing concrete frame buildings, all specimens were constructed with normal-weight concrete with the design compressive strength of 18 MPa.

Introduction With the social progress and booming economical development, the demand of conventional construction materials such as steel and concrete are at an unprecedented level throughout the world.
However, the processes of producing these materials usually accompany with high energy consuming and severe environment pollution.
(1) We consider the following values for the following parameters: Cross-sectional areas of materials A and B, AA=0.8Atotal,AB=0.2Atotal, compliances of materials DA=1/15GPa-1, DB=1/22GPa-1, creep coefficient ΦA=5.0，ΦB=2.5, τA=500days and τB=1000days, the stress applied on the piers is 0.1Mpa.
