Embodiment Construction

[0044] The present invention will be further described below in conjunction with the examples, but it should not be understood that the scope of the subject of the present invention is limited to the following examples. Without departing from the above-mentioned technical ideas of the present invention, various replacements and changes made according to common technical knowledge and conventional means in this field shall be included in the protection scope of the present invention.

[0045]This embodiment aims at the problems existing in the existing steel bar collision detection technology that can only detect the collision but cannot automatically adjust the position of the steel bar, the calculation time is long, and the accuracy is insufficient. question. Treat each rebar as an animatable agent. The movable agent starts from the starting point of each steel bar, and the target point is the end point of the steel bar.

[0046] see figure 1 , the present embodiment discl...

Abstract

The invention provides an automatic reinforcing steel bar obstacle avoidance method based on an artificial potential field method in an intersection region of reinforced concrete components. The method comprises the following steps: expressing reinforcing steel bars and components at nodes in a discretization manner, intelligently arranging reinforcing steel bars of a main beam in one direction byusing an artificial potential field method, intelligently arranging reinforcing steel bars of a main beam in another direction by using the artificial potential field method, storing as a reinforcingsteel bar central line coordinate, adjusting the reinforcing steel bar central line coordinate, and outputting the adjusted reinforcing steel bar central line coordinate. By adopting the method, theproblems that in a conventional reinforcing steel bar collision detection technique, only collision can be detected, positions of reinforcing steel bars cannot be automatically adjusted, the automaticlevel is low, the precision is insufficient, and the like, can be solved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to an automatic obstacle avoidance method for steel bars in intersecting areas of reinforced concrete components based on an artificial potential field method. Background technique [0002] Reinforced concrete structures are structures made of concrete reinforced with steel bars. Rebar is in tension and concrete is in compression. The reinforced concrete structure has the advantages of firmness, durability, good fire performance, less steel and lower cost than the steel structure. The design and construction of reinforced concrete structures are two important stages of a construction project. The reinforcement design of reinforced concrete members is often only related to the stress conditions, boundary conditions and member dimensions of the members. During the design phase, especially in complex beam-column joints, architectural designers usually do not consider the proble...
