Abstract

Abstract:

To study the mechanical properties of high-strength steel reinforced concrete columns under large eccentric loading， and to determine the stress state and the compressive strength level of a new developed 630 MPa ribbed high-strength steel， 17 concrete columns reinforced with 630 MPa high-strength steel tested under large eccentric compression were fabricated， and the failure pattern， lateral deflection， strain of steel and concrete， and the bearing capacity were analyzed. The results show that the typical failure pattern of 630 MPa high-strength steel reinforced concrete column with large eccentric compression is the same as that of ordinary reinforced concrete column. The ultimate compressive strain of concrete compression zone is greater than 0.0033 in the current code， which is conducive to give full play to the compressive strength of 630 MPa high strength reinforcement in eccentric compression member， so that the compressive strength reaches the same value as the tensile strength. The test value of bearing capacity of each specimen is much higher than its design value， with an average value of the ratio of 1.887. It is reasonable and safe to design and calculate the 630 MPa high strength reinforced concrete column members by using the current specification. The tensile and compressive strength design values as 545 MPa of the 630 MPa high-strength steel in column member subjected to eccentricity is put forward， providing an experimental basis for the compilation of technical specification for high-strength bar in concrete structures and the promotion of 630 MPa high-strength steel in engineering application.

Key words: structural engineering, 630 MPa high-strength steel, large eccentric compression, high strength reinforced concrete column, compressive strength, bearing capacity
