Engineering Software / Civil Digital Transformation🧱 I used AI to create a structural mechanics solver, and it only took 2 hours.
Last night our non-deconstructive mechanics master used GAMA’s built-in structural mechanics solver to conduct a parametric analysis:
Rhino and YJK finally achieve real-time linkage, and it’s bidirectional!
I believe that many structural engineers cannot put down their love for Rhino. Its powerful geometric processing capabilities and the numerous algorithm resources brought by its openness, combined with a visual programming platform such as Grasshopper, can greatly improve the work efficiency of our structural engineers. However, since it is not yet present in the structural engineer’s workflow
Revit and YJK have finally achieved real-time linkage!

When structural design meets machine learning
For the majority of structural engineers, machine learning seems to be a word that is both far away and very close to us. It is said that it is far away from us because most engineers have only heard of some related concepts in general. They only know that it is widely used in scenarios such as image recognition and semantic recognition, but they do not understand how these so-called machine learning can be used in our actual work.
When structural design encounters genetic algorithms, it learns to evolve on its own!
A long, long time ago, the editor only heard about genetic algorithms in legends, but I had no idea what this thing was. I just felt in my heart that this should be a very awesome existence. What was going on and what was its use? I couldn't figure it out. . .
Remote working guide for design institutes-Using Alibaba Cloud to build a team collaborative work platform
With the recent outbreak of the new coronavirus, I believe many design teams have adopted the work-from-home model. Although online communication and conferencing apps such as DingTalk and Enterprise WeChat have filled our daily life of working from home, they can meet our daily work communication and meeting needs. But for architects and engineers, working from home prevents us from logging into our company servers.
Non-deconstruction | In-depth thinking on BIM workflow
In the current architectural design industry, many practitioners or units are aware of the significance of BIM forward design to the architectural design industry. Through BIM, collaborative work among various disciplines such as architecture, structure, plumbing, heating, and electricity can be realized, and the linkage between disciplines can be improved. Many design units have also established corresponding departments such as BIM centers or digital design centers to try
DB Browser for SQlite-Ying Jianke’s alternative solution
The significance of YJK to current structural engineers is self-evident. The relatively friendly interface, relatively rich functions, etc. all play a key role in improving the work efficiency and work quality of structural engineers.
Parametric analysis of steel structure support end gusset plate based on secondary development of ABAQUS
Strong nodes and weak components are the general principles of building structure design. Steel structure node connection In the design of steel structure, there are two main ways of connecting beam-column nodes with diagonal braces, as shown in Figure 1 and Figure 2. Among them, the node connection method shown in Figure 1 basically maintains the original shape of the component at the node, and its load-bearing capacity is relatively reliable. However, its production and construction are relatively complex, and the beams and columns support
N ways to draw small circles in CAD—CAD secondary development guide
For all drawing dogs who use CAD to draw, just drawing a circle does not seem to be a difficult task. Click the command bar, click the toolbar, and enter the shortcut key directly. . . When seeing this title, the drawing dogs may laugh and say Are you kidding me? ! Is this topic worthy of writing a public account? ! !
Parametric analysis methods and cases based on ABAQUS
With the development of technology to this day, the concept of parametric analysis has been deeply rooted in people's hearts. You only need to define a few parameters and relevant scripts, and the originally complicated work can be completed once and for all. Similarly, when performing finite element analysis, using relevant scripts for parametric modeling analysis can greatly improve our analysis efficiency. Today I will introduce to you some information based on pyt
One-click drawing and batch binding - CAD you don’t know
1) When it comes to printing pdf using cad, it is self-evidently painful for Paintdog without any plug-ins. The average small project is okay, but it seems impossible to print hundreds of drawings one by one without setting aside a day and finding a few helpers. Of course, in order to solve this problem, plug-ins such as Bitch Toolbox also integrate batch printing functions.
YJK steel structure node design internal force reading tool
Node design is a crucial link in the internal force design of steel structures. In the past, when designing nodes, it was necessary to check the internal force of each steel structure member. When drawing node details, the structural engineer's style is to look at the results file of the computational model over and over again. It’s just a small house with one or two floors. When faced with a large number of high-rise and super high-rise buildings with a wide range of areas, it is not only inefficient;
When an architect throws me a Rhino model—
For general conventional projects, vertical sections and appropriate communication with the architect are sufficient as background information for the establishment of structural models. But when I received the funding proposal for a building plan like Figure 1, the editor was confused. Is this obviously a topographic map? I felt deeply helpless~~~ At least let’s get a three-dimensional model~~~
When an architect throws me a rhino model (2)
Faced with a complex irregular concrete shell with a total length of about 50m and a height of 45m, we discussed the use of Rhino and ABAQUS conceptual analysis interfaces, Grasshopper to develop Rhino to SAP2000 automatic mold transfer and attribute assignment interfaces, and the entire process of node coordinates and steel structure three-dimensional solid lofting drawings.
For OPENBIM, is IFC enough?
How to connect the traditional architectural design process through BIM to improve the quality and efficiency of the entire design process? This topic has been discussed and studied by many designers and engineers. There are currently two mainstream solutions:
Play with IFC through Blender
Ifc (Industry Foundation Classes), as the most popular general BIM data standard at the moment, contains all aspects of data in the entire life cycle of construction projects, from design planning to construction operation and maintenance. IFC started in 1994 and was organized by buildingSMART (formerly known as International Interoperability
Build your own Midas and YJK interfaces
Many days ago, the editor received a Rhino model and hoped to transfer the Rhino model to YJK through YJK-GAMA to generate a YJK model. This operation is a piece of cake for YJK-GAMA.
Spatial structure form finding analysis (2)—force density method form finding
What is the significance of form-finding analysis of structures? Let’s look at two cases:
Seismic wave conversion response spectrum with source code attached
5.1.2 of the Building Seismic Design Code (GB50011-2010, hereinafter referred to as the Code) stipulates that for particularly irregular buildings, Category A buildings, and high-rise buildings within the height range listed in Table 5.1.2-1, the time history analysis method should be used to perform supplementary calculations under frequent earthquakes;
Non-deconstruction | Application of parametric design of building structure in low-density courtyard projects
Abstract: With the development of parametric architectural design technology, parametric design of building structures is increasingly being used in complex long-span structures and super high-rise structure projects. In conventional low-density courtyard-type projects, there are also scenarios where parametric design technology for building structures is applied. This article uses a certain project as the background to systematically study and develop the parametric design of a low-density courtyard project.
