Embodiment 1

[0035] Embodiment 1: as Figure 1-3 , a reinforced concrete fire-resistant test piece, which is formed by connecting two columns and a beam; the two ends of the beam are rigidly connected with the tops of the two columns (that is, an integral cast member); The beams and columns are reinforced concrete components; the thickness of the protective layer of the beams and columns is 35mm-40mm.

[0036] The longitudinal reinforcement in the beam and column adopts threaded steel bar with a diameter of 10-16mm; the stirrup adopts round steel with a diameter of 8-12mm; the spacing between the stirrups is less than 15 times the diameter of the longitudinal reinforcement. (the stirrups are multiple, arranged at equal intervals along the longitudinal bars, not only figure 1 9 of them, represented by 3 stirrups is a brief representation of the reinforcement diagram)

[0037] There are 5 longitudinal reinforcements in the beam and 4 longitudinal reinforcements in each column.

Embodiment 2

[0041] Embodiment 2: as Figure 1-3 , a design method of a reinforced concrete fire test piece, using a composite frame member as a reinforced concrete fire test piece to improve the fire resistance and bearing capacity of the test piece;

[0042] The reinforced concrete fire-resistant test piece of Example 1 is used as the composite frame member.

Embodiment 3

[0043] Embodiment 3: as Figure 4-7, a test system for reinforced concrete fire-resistant specimens, including a fire test furnace 8, a specimen 6, a fixed hinge support and a load application device [for a rigid member, there are three degrees of freedom, that is, the horizontal degree of freedom and the vertical degree of freedom degree and rotation degree of freedom, while the fixed hinge support can restrict its two degrees of freedom, namely horizontal and vertical, and cannot restrict rotation. 】;

[0044] Put the test piece 6 vertically into the fire test furnace 8, clamp the test piece in the middle with two left and right cover plates 9 above the fire test furnace to prevent the lateral displacement of the test piece 6, and use a The fixed hinge support fixes the test piece to prevent horizontal displacement of the test piece; after fixing the test piece, start the fire test furnace to keep the temperature in the fire test furnace constant, apply a load through the l...

Abstract

The invention discloses a reinforced concrete fire-resistant test piece, a design method, a testing system and a testing method. The reinforced concrete fire-resistant test piece is formed by connecting two pillars and a beam; both ends of the beam are rigidly connected with the top ends of the two pillars (i.e. the reinforced concrete fire-resistant test piece is a component which is formed by integrated casting); both the beam and the pillars are reinforced concrete components; protection layers of the beam and the pillars have thicknesses of 35mm to 40mm. The reinforced concrete fire-resistant test piece adopts a beam and pillar combination frame structure, has more excellent fire resistance than a test piece adopting a single form, and has high bearing capacity.

Description

technical field [0001] The invention relates to a reinforced concrete fire-resistant test piece, a design method, a test system and a method. Background technique [0002] In order to study the fire resistance of reinforced concrete specimens, in the past, relatively simple components were designed, such as single components such as beams, columns, and slabs. Their mechanical properties are relatively simple, their fire resistance is relatively poor, and their bearing capacity is low. [0003] Therefore, it is necessary to design a new reinforced concrete fire resistance test piece, testing system and method. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a reinforced concrete fire-resistant test piece, a design method, a testing system and a method. Better performance, large bearing capacity. [0005] The technical solution of the invention is as follows: [0006] A reinforced concrete fire-resistant test pi...
