Steel shear wall (SSW) was properly determined using numerical and experimental approaches. The properties of SSW and LYP (low yield point) steel shear wall (LSSW) were measured. It is revealed that LSSW exhibits higher properties compared to SSW in both elastic and inelastic zones. It is also concluded that the addition of CFRP (carbon fiber reinforced polymers) enhances the seismic parameters of LSSW (stiffness, energy absorption, shear capacity, over strength values). Also, stress values applied to boundary frames are lower due to post buckling forces. The effect of fiber angle was also studied and presented as a mathematical equation.

This paper is about practical tensile testing of structural steel S355. There are many European grades of structural steel such as; S195, S235, S275, S355, S420, S460 etc. The maximum chemical composition of structural steelS355 is 0.23 C, 1.6 Mn, 0.05 P, 0.05 S and 0.05 Si. Mechanical properties of structural steel S355 are yield stress of 355 MPa and ultimate stress of 470 to 630MPa according to European Committee for Iron and Steel Standardization. There are many types of material testing such as tensile test, compression test and other test etc. Material testing is of extreme importance that the user of materials be able to obtain reliable information on the properties of materials. Material testing is one of the helping functions of engineering fields. It is really necessary and important for a country in order to become more developed. Without it, all engineers are faced the problem. The yield point, and ultimate strength of structural steel S355were determined in uniaxial tension. The specimen geometry was used with the region of minimum cross section having the dimensions: diameter is 6 mm and gauge length is 10 mm. Three fundamental mechanical properties of metals are modulus of elasticity (E), yield stress (σ y), and ultimate stress (σ u). The lower limit of yield point was determined to be 374.882 MPa. The upper limit of the yield point was determined to be385.094 MPa. The ultimate stress was determined to be 628.278 MPa.
