Practical application of finite element simulation in civil engineering

As one of the earliest engineering disciplines, civil structure engineering covers a wide range of scientific and technological fields. Civil engineering is an important field in the application of finite element analysis. The strength, life and reliability analysis of civil engineering equipment and the finite element simulation of civil engineering in the process of drilling, digging, mining and construction are very deep in the field of structural engineering.

Typical application in civil engineering field

Civil architecture is a complex and challenging subject that requires the integrated application of theories and methods from multiple disciplines. From civil construction, bridge structure, hydraulic structure, highway, tunnel, underground engineering and other aspects are inseparable from structural design and finite element analysis and calculation.

☑️ Cracking strength of fiber reinforced concrete bridge panel ☑️ seepage flow in culvert pipe of earth dam ☑️ strength of external prestressed concrete box girder ☑️ The hyperbolic cooling tower is demolished by blasting

☑️ exposed pillar stiffness ☑️ platform strength ☑️ Ferris wheel complete machine ☑️ steel web box girder prestressed ☑️ beam column joints and construction joints seismic resistance ☑️ steel support bearing capacity

Finite element simulation of bridge construction process

In bridge construction, ABAQUS provides functions such as Model Change, reinforced concrete material properties, and reinforcement preload. The figure below is a finite element simulation of the construction process of a bridge.

The bridge is 140m long and 80m high. The first and fourth modal modes of bridge modal analysis are shown in the figure below.

Finite element simulation of Jingsha Yangtze cable-stayed bridge in Chongqing

The main bridge of the South branch navigation hole of Jingsha Yangtze River Highway Bridge, located in Jingzhou City, Hubei Province, is shown in the figure below. The main span is arranged as 160+300+97m, and the total length of the bridge is 557m. The following figures are the simulation of the construction process, structural dynamic response and seismic response analysis results of the bridge by using ABAQUS.

Finite element simulation of steel stairs

For some special purpose stairs that do not meet the applicable conditions of National standard Atlas 15J401 "Steel Ladder", usually the section size of its members, nodes and reaction forces can not be directly selected from the diagram set, so it is necessary to establish a finite element model according to the finite element theory, and carry out finite element simulation analysis of its overall strength and deformation under the static load. The calculation verifies the correctness of the design of the staircase structure, and provides design guidance for the appearance and structure of the staircase based on this. Analysis focus: beam section definition, offset, and geometric nonlinear solution parameter adjustment.

Simulation of air flow organization in clean workshop and hospital ward

In areas such as electronics plants, clean workshops, data centers, and biomedicine, clean space is a key facility. These plants need to maintain specific cleanliness levels and temperature and humidity to ensure product quality and smooth process. The air flow organization in the room is an important factor affecting the cleanliness of the room, the number of suspended particles, the uniformity of temperature and humidity, the pressure difference, and the energy consumption of air conditioning. In order to achieve this goal, CFD air flow analysis simulation software is used in the design stage or the construction deepening design guidance stage to conduct finite element simulation analysis of the air flow organization scheme, and it is very important to understand the air flow distribution and the transmission mechanism of pollutants. Provides valuable insights for design, optimization, and management.

Data center air flow analysis simulation

With the rapid development of the data center industry, the density of IT cabinets continues to grow, and the increase in the density of IT cabinets has increasingly stringent requirements for air flow organization in the machine room. For the air flow organization of the IT room, it is now a common practice to divide the hot and cold channels, and whether the hot and cold channels are closed or not has been a controversial issue in the industry. After all, the closure of hot and cold channels will bring a large cost increase, and in the case of low density, the cost-effectiveness ratio may not be worth the loss.

Diversified service types

Including project undertaking, hardware and software selection and configuration, specialized customized secondary development, technical training, project navigation, personnel training, fixed-point technical support, etc., to maximize the benefit of customer investment.
