Example Embodiment

[0079]Embodiment;

[0080]Such asfigure 1 As shown, (1) Define the probability of the particle size distribution of the aggregate;

[0081](2) Define the type of aggregate and aggregate parameters;

[0082](3) Define the aggregate model parameters, the desired parameter algorithm is as follows:

[0083]Percentage = 0.40, the percentage of the outermost proximal aggregate;

[0084]RockRadio = [0.35, 0.65], the percentage of aggregates [Natural aggregate, regenerated aggregate];

[0085]Boxx = 50, model X direction size;

[0086]Boxy = 50, model Y direction size;

[0087]Dlevel = [25, 20, 15, 10], the length of the long axis of the ellipse range;

[0088]StoneOLDFACE = 0.3, thickness of the aggregate and old mortar interface;

[0089]Holdmortar = 0.8, old mortar thickness;

Abstract

The invention discloses a construction method of a recycled concrete oval random aggregate model. The construction method is specifically carried out according to the following steps: 1, statements for generating an oval aggregate model are compiled through a Python language, and oval recycled aggregate and oval natural aggregate are established; 2, the oval recycled aggregate and the oval naturalaggregate are extracted by using a random sampling method, aggregate particle sizes are generated, a particle size generation algorithm is written by using a Python language, recycled aggregates withdistributed particle sizes are generated, and the recycled aggregates with distributed particle sizes are input into a particle size library; 3, the aggregates are put from large to small; 4, modeling is conducted through Python statements, and 5, ABAQUS post-processing is conducted through a Python language, and the model is stored. The method is simple and quick to operate, relevant parametersand material attributes of the model can be flexibly changed, simulation of the oval recycled concrete random aggregate model is achieved, and the method better meets the requirements of an actual simulation test model.

Description

technical field [0001] The invention belongs to the technical field of recycled concrete, and in particular relates to a method for constructing an elliptical random aggregate model of recycled concrete. Background technique [0002] In the field of contemporary architecture, concrete is widely used. With the development of my country's urbanization process, the demolition of old and new buildings has brought a lot of concrete waste. These construction wastes can be recycled to produce recycled concrete, which can be used in road works, low-rise buildings and other projects, thus solving the pollution and disposal problems caused by waste concrete. [0003] So far, many scholars have conducted a large number of experiments on the research and application of recycled concrete, such as changing the preparation of recycled concrete and other methods to study the influence of different aggregate replacement rates and concrete preparation methods on the basic mechanical properti...
