Dear Honorable Lecturers

The Faculty of Civil Engineering and Planning – Petra Christian University

We would proudly invite you to DEACE International Workshop - Bamboo Grid Shell Computational, in our Plenary Courses:

*These plenary courses can be accessed by following the links above and will lead you to Microsoft Teams meeting. You can choose to join the meeting via Team's website, so you don’t have to create a Microsoft Teams id first.

Plenary Course 1: Grid shell: Basic Principle and Design

(August 12th, 9.30 AM) > Link:

Speaker: Wen-Shao Chang - University of Sheffield

The course will explain and discuss the definition of grid shell structure and the design principle of the grid shell structure. The discussion will include the definition and type of grid shell structure, the case study from existing grid shell structures, and the material. The course will also address the method of form finding of grid shell structure and if the allocated time is sufficient, discussion related to the construction method (strained or unstrained) will be accommodated.

Plenary Course 2: Bamboo as Building Material

(August 12th, 11 AM) > Link:

Speaker: Esti Nurdiah

The course will provide basic knowledge of bamboo utilization for building as a structural material. This will include the characteristic of bamboo that a designer should consider when designing a building or structure using bamboo; such as bamboo anatomy, physical properties, and mechanical properties. The course also will explain the correlation and implication of the bamboo properties to the design process.

Plenary Course 3: Structural Analysis of Gridshell Structure (part 1)

(August 13th, 9 AM) > Link:

Speaker: Wong Foek Tjong

Fundamentals of Shell Structures and Structural Analysis

The lecture will first introduce different types of shell structures, that is, continuous, stiffened, and grid shells. These include the definitions, advantages/disadvantages, and several examples.

The second part of the lecture will present the fundamentals of structural analysis, specifically, the basic knowledge an engineer should know for analyzing grid shell structures. These include the analysis cases, mathematical models, material properties, and loadings.

Plenary Course 4: Form-finding of Gridshell Structure

(August 13th, 1 PM) > Link:

Speaker: Esti Nurdiah

Description: This course will focus on the form-finding method of grid shell structure using Rhinoceros with plug-in Grasshopper and Kangaroo. The participant can learn how to operate form using parameters in Grasshopper and Kangaroo.

Plenary Course 5: Structural Analysis of Gridshell Structure (part 2)

(August 16th, 10.30 AM) > Link:

Speaker: Wong Foek Tjong

FiniteElement Analysis of Grid Shells

This lecture will present an overview of the finite element method for analyses ofstructures. Examples of finite element structural analysis using SAP2000 Ver.23 commercial software will be discussed.


The workshop is a 5-day online workshop (12,13,16,18,21 August 2021) delivered in English and opens for Architecture and Civil Engineering students from universities in Indonesia and abroad. The program comprises of lectures, discussions, group work, exhibition and final presentation at the DEACE International Conference. The workshop equals to a regular course of 3 credits (43 hours). Participants will be benefited from international exposure and received lectures from bamboo expertise and also tutors from architecture and civil engineering. Students will work in groups and propose a design problem by applying computational design for bamboo.


  • To introduce bamboo as a building material, especially for freeform architecture, and basic principle of gridshell structure.

  • To investigate form finding methods for gridshell structure using model.

  • To assess the construction process and joineries for gridshell bamboo by building a prototype.

  • To evaluate the structure stability and strength using model and prototype.


Bamboo, one of local materials in Indonesia, has been used as a building material for centuries by local people. Bamboo is a sustainable material due to its role in carbon sequester. It releases oxygen during the planting period, needs low labour in harvesting, and can be regrowth in a short period. The fast growth aspect makes bamboo is considered more sustainable than wood. The potential of bamboo as building material not only lies on sustainability but also on the mechanical properties and flexibility, thus bamboo is potential to be used for freeform architecture. However, to utilise bamboo needs knowledge and understanding on the characteristic and properties of bamboo.

Gridshell is one of shell structure that can be defined as basically a shell structure with holes, which the loads are concentrated to strips and gains its strength and stiffness through its double curvature configuration (Chilton & Tang, 2017; Harris, 2011). Gridshell structure is commonly using timber lath as the strips, e.g. Mannheim Gridshell, Downland Gridshell, Savill Garden Gridshell, or steel. Other materials have been used for gridshell structure, such as paper tube, and bamboo, but the buildings were only for temporary function.

Gridshell structure produces a shelter with long eaves which is suitable for the climate in Indonesia; while bamboo gives familiarity and identity as local architecture for the building. However, to utilise bamboo for gridshell structure need further study. Raw bamboo is round, hollow, uneven and tapered while mechanical properties of each bamboo are varied. To design a gridshell structure using raw bamboo need further understanding of the structure and bamboo.

This workshop aims to give knowledge of bamboo and gridshell structure through experimental study. Students/participant will gain knowledge through experience in lectures and workshops.


The minimum second year of undergraduate students preferably from Architecture or Civil Engineering major (postgraduate and professionals are also welcome)
