(A) brittle damage (B) plastic damage (C) damage damage (D) The basic mechanical properties of the structural steel should be C. A) tensile strength, elongation (B) tensile strength, yield strength, cold bending performance (C) tensile strength, yield strength, elongation (D) yield strength, elongation, cold bending performance Welding residual stress C when the steel has better plasticity. Reducing the static strength of the structure (B) increases the static strength of the structure (C) the static strength (D) of the structure shall be determined according to the actual conditions The effective thickness of the vertical fillet weld is A. (A) 0.7 (B) 4mm (C) 1.2 (D) 1.5 The strength and stability of the axial compression bar should be satisfied with B respectively. (A) (B) (c) (D) In the formula, A is the area of the hair section of the bar. The An is the net area. The arrangement of the stiffening rib increases the local stability bearing capacity of the girder, at the time C. (A) the shear instability may occur and the lateral stiffening rib should be configured (B) it is only possible to have the bending and instability, and the vertical stiffening rib should be configured (C) both vertical and horizontal stiffening ribs should be configured at the same time (D) the most reasonable measure is to increase the thickness of the abdominal plate The shear force should be taken C when calculating the infix of the lattice bending member. (A) the actual shear design value of the component (B) the shear force calculated by the formula (C) the value of the actual shear-force design or the shear force calculated by the formula are the larger of the two (D) by the calculated value When there is a fixed large concentrated load on the beam, the a
