摘要
本文主要研究钢筋混凝土板与地基相互作用的模型问题。这是一项具体的任务，包括混凝土结构设计和岩土分析。本文的目的是分析地基参数在非线性分析中的作用。具体来说，对不同土层深度和弹性模量进行了参数化研究。为了进行数值模拟，选择了尺寸为2000 x 2000 mm，厚度为150 mm的钢筋混凝土板的实验，并在俄斯特拉发技术大学的专用设备上进行了测试。混凝土板用钢筋加固。三维数值模型采用有限元方法进行非线性分析，其中混凝土采用断裂塑性材料模型。
REINFORCED CONCRETE SLAB WITH SUBSOIL: NUMERICAL MODELLING AND EXPERIMENT
: The paper is focused on the issue of modelling reinforced concrete slab in the interaction with the subsoil. It is a specific task that includes the design of concrete structure and geotechnical analysis. The aim of the paper is to analyze the effects of parameters of subsoil in nonlinear analysis. Specifically, a parametric study for different subsoil depths and subsoil modulus of elasticity is elaborated. For numerical modelling, an experiment of the reinforced concrete slab with dimensions of 2000 x 2000 mm and thickness of 150 mm was chosen, which was tested on a specialized device at Technical University of Ostrava. The concrete slab is reinforced with steel reinforcement. Nonlinear analysis with utilization of finite element method is chosen to solve the 3D numerical model, where the fracture-plastic material model is chosen for concrete.
