2. INTRODUCTION
Sky classroom is a course that focuses on teamwork, ever since the project began, we have been worked together continuously, and it is also our first time to cooperate with people in other country so that we can only discuss with them with communication software, such as: sococo, whatsapp, and so on. Though we’ve encountered a lot of difficulties in the process, but we conquered them all in the end. This report is about the effort we’ve made in these days, and it will cover four parts which are Project goal, Discussion, Project results, Lessons learned& conclusion.
3. PROJECT GOALS
During this project, we have finished a series of work. It would be difficult to list every single one, so we’ll bring you the main goals we put our best efforts in so that we can achieve them.
- 3D models:
In the very beginning of the project, we received 3 revit models, so the first thing we have to do is that building up the 3D models respectively in etabs, and, in consequence, we have to learn how to build the models in etabs. By watching videos, going lectures and discussing with each other, we eventually have a basic concept of etabs, and built the models on our own successfully. - structural analysis:
After finishing the 3D models, we have to analyze our structures to assure that they won’t fail the test. In this phase, we repetitively adjust and check the section size of each beam, because we’ve considered various factors, such as: the cost, whether it is convenient in the construction process, etc. We’ll show you more of the details in the following content. - cost assumption:
Considering it is designed for the refugees, the top priority for us is to reduce the budget as much as possible, so we roughly estimate the cost of each building to see if the outcome meets our requirements.
4. TOOLS
The most important thing in this project is about “discussion”, since there several teammates are American, we can only discuss with them through the internet. In the beginning we use 4 tools to discuss with them:
- Whatsapp:
This is a very useful app because we can communicate with each other immediately. - Email:
After we finished our 3D models, we send them our results through email. - Sococo:
We used this in our kick-off meeting. - ETABS:
We used this to make model and structure analysis.
5. PROJECT RESULTS
3D models
Load
- Dead Load self-weight (x 1)
We multiply dead load by 1 because we consider its weight automatically. - Reducible Live
We use reducible live load instead of live load because we consider that live load will not reach the maximum limit. Thus, if we use reducible live load, the design will be economical. - Cladding
We add cladding load because we consider the weight of external walls. Thus, the design will be close to reality. - Earthquake force
We add earthquake load in type of seismic based on ASCE7-10.
3 types of load combinations:
We use three types of load combinations to analyze the structure. The load combinations are shown below:
- COMB1 = 1.4(DL + SPDL)
This combination considers dead load and super dead load. - COMB2 = 1.2(DL + SPDL) + 1.6LL
This combination considers dead load, super dead load, and reducible live load. - COMB3 = 1.2(DL+SPDL) + 1.1LL +1.0 EQ
This combination considers dead load, super dead load, reducible live load, and earthquake load.
Design & Analysis procedur
- Modeling
We built the model and assigned frame and deck to the model. Also, we assigned load patterns and load combinations. - Design section
We used frame check and beam check to check whether the sections follow the regulation. - Add bracing
For some complex structures, if they failed to pass the check, we tried to add some bracing there to help them pass the check. - Change section
We tried to change most of sections to similar size in order to make the design more economical.

Total cost: 3519133 (g=10 m/s2)
3519133*10/9.8=3590951.966
Total cost: 3590952 (g=9.8 m/s2)
3519133*10/9.8=3590951.966
Total cost: 3590952 (g=9.8 m/s2)

Special case:
Special design:
|
At first, we thought that this design would not be safe because there is not any secondary beam. However, when we ran the analysis, we found that there is smaller displacement. Furthermore, we can use better sections that can always pass the check. Lastly, this design would be easy for construction and make it economical.

Design & Analysis
While doing the structure analysis, we found that bracing is really a good idea for structure design. The reason is that it can resist lateral force, which we can select smaller frame section rather than using larger section. Thus, our design will be more economical.
Speaking about economical, after we learned about what the frame section number means (W depth X weight per unit length), we chose frame section by the principle of bigger first number and smaller second number. Also, in order to let the construct be easy, we tried our best to make the frame section more consistency.

6. DISCUSSION
We have learned a lot in this lecture. First, we learned how to use ETABS to model a building and do its structural analysis. Second, we learned to cooperate with our teammates in Taiwan and US. Besides, the lecture had goals every week, we planned our time doing project to meet the goals, which was a great experience. At last, we also practiced making presentation and reports.
This lecture is really meaningful to us, since we get familiar with steel structure and some useful software, including ETABS, Sococo, Whatsapp. However, we think our communication with WSU teammates isn’t enough at all, we really hope that we can have more opportunities to discuss with them, and the project might be more interesting and special.

7. KEY FACTORS TOWARD A SUCCESSFUL INTERNATIONAL COLLABORATION PROJECT
- Make good use of communication tools (sococo, email, whatsapp)
- Follow the schedule
- Stand in others’ shoes:
Consider WSU teammates’ difficulties
