Problems solved by technology

A certain effect can be achieved when the span is not very large, but there are the following problems: ①Increase the amount of materials, and the economy is poor; ②It affects the use function of the structure; ③The self-weight of the structure increases, which is equivalent to the increase of the load, and the frame beams and columns. The bending moment increases again, and at the same time brings difficulties to the construction
Although the replacement of frame beams with structures suitable for large spans such as trusses can achieve the purpose of large spans, it is difficult to make rigid connections between trusses and frame columns, and the frame structure system cannot be formed, and the overall horizontal stiffness is small; at the same time, the structural height of trusses is relatively small The frame beam is much larger, which affects the use and function of the structure

Embodiment 1

[0039] Such as figure 1 , Figure 9 As shown, the reinforced concrete frame structure with haunch bracing is formed by the rigid connection of frame beam 1 and frame column 2. , the lower ends are rigidly connected to frame beam 1 and frame column 2 respectively; the inner angle α between the axis of arm brace 3 and the axis of frame beam 1 1 , the inner angle α between the 3-axis of the arm brace and the 2-axis of the frame column 2 It can be determined according to the requirements of structural design, so that the force of the structure is reasonable and meets the requirements of the use function. The reinforced concrete frame structure with haunch supports can be single-span or multi-span, single-story or multi-layer; multi-span can be equal or unequal span, and the height of multi-layer can be equal or unequal. figure 1 The frame beam span of the middle frame structure is taken as L=29500mm, and the frame column height is taken as H 1 =8900mm, H 2 =8700mm, inner angl...

Abstract

The present invention provides a reinforced concrete frame structure with angle braces. The reinforced concrete frame structure is made up by using frame beams and frame columns which are rigidly-connected together, and the every nodal point where every frame beam is rigidly-connected with every frame column is respectively equipped with the upper part and the lower part of the angle brace, an axis of the angle brace has an inner included angle alpha1 with an axis of the frame beam, and the axis of the angle brace has an inner included angle alpha2 with an axis of the frame column according to the requirement of the structural design; the reinforced concrete frame structure with angle braces can be single span or multi-span, single layer or multi-layer; wherein multi-span can be equal span or unequal span, and the story height of the multi-layer can be equal or unequal. The invention has good mechanical behavior, good economical efficiency and good application property, and is suit for long span structure system.

Description

technical field [0001] The invention relates to a reinforced concrete frame structure of a structure and its structure, in particular to a reinforced concrete frame structure with arm braces. Background technique [0002] The reinforced concrete frame is composed of frame beams and frame columns, and the joints of frame beams and frame columns are rigid joints. The frame can be single-span or multi-span, single-layer or multi-layer; multi-span frame can be equal span or unequal span, and the layer height of multi-layer frame can be equal or unequal. The reinforced concrete frame of the building generally has a roof panel on the frame beam, and the frame structure system is formed by a multi-frame frame to bear the external load. The reinforced concrete frame beams of other structures may or may not have slabs, and the external loads may be borne by a single frame or a frame structure system formed by multiple frames. Due to its good economy, constructability and applicabil...
