EXPERIMENTAL STUDIES ON SHEAR RESISTANCE PERFORMANCES FOR THE SHEAR KEY OF H SHAPE STEEL SPATIAL GRID ROOFS

Authors

Abstract

IN THIS PAPER, A NEW TYPE STRUCTURE WAS INTRODUCED. THE SPATIAL STEEL GRID STRUCTURE WAS MADE UP OF THE TOP LAYER, LOWER LAYER H-SHAPED STEEL RIBS AND SQUARE STEEL TUBE. THE SHEAR BLOCK IS THE KEY PART OF STRUCTURE．BASED ON THE REAL SIZES OF A PROJECT，TWO SETS OF FULL-SCALE SHEAR KEY SPECIMENS WERE MADE. ONE HAS VERTICAL STIFFENING RIBS, AND THE OTHER HAS NOT. SIMULATING THE LOADING CONDITIONS UNDER PURE SHEAR, THE LOADING TESTS OF TWO GROUPS OF SPECIMENS WERE CARRIED OUT, AND THE EXPERIMENTAL DATA WERE COMPARED WITH THE FINITE ELEMENT ANALYSIS DATA. THE EFFECTS OF VERTICAL STIFFENERS ON FAILURE MODES, ULTIMATE LOADS, STRENGTH-YIELD RATIO AND DUCTILITY OF SHEAR KEY ARE STUDIED THROUGH EXPERIMENTS. THROUGH PARAMETRIC ANALYSIS, THE REASONABLE WIDTH AND THICKNESS OF VERTICAL STIFFENING PLATE ARE PROPOSED.
