Struktur tensegrity ialah sebuah struktur di mana ahli mampatan disambungkan oleh ahli tegangan. Struktur ini menunjukkan ketegarannya melalui keseimbangan diri di antara ahli mampatan dan ahli tegangan dengan memperkenalkan pra-tekanan. Pembinaan struktur tensegrity amat mencabar disebabkan tahap sensitivitinya yang tinggi dan ketidakstabilan bentuknya semasa proses pembinaan. Namun, kajian tentang urutan pembinaan struktur tensegrity skala penuh agak kekurangan. Oleh itu, kajian aplikasi hasil penentuan bentuk dan pra-tekanan kepada pembinaan struktur tensegrity termasuk pertimbangan isu praktikal amat diperlukan. Tumpuan kajian ini merupakan tensegrity prisma pelbagai lapisan secara tidak seragam. Kaedah pengiraan komputer yang menggunakan pendekatan linear dengan menggabungkan syarat hubungan panjangnya dan persamaan keseimbangan daya telah digunakan dalam proses penentuan bentuk dan pra-tekanan. Daya pra-tekanan di dalam kabel diperkenalkan melalui pemanjangan kabel. Urutan pembinaan struktur tensegrity telah dikaji dan ditambah baik melalui pembinaan model fizikal. Kesan urutan pembinaan pada konfigurasi muktamad struktur tensegrity prisma pelbagai lapisan telah dikaji. Urutan pembinaan yang terperinci mengenai struktur tensegrity prisma pelbagai lapisan telah dicadangkan.

Tensegrity structures are structures where its compression members (struts) are connected by continuous tension members (cables). The structure shows its rigidity through the self-equilibrium between the struts and the cables with the introduction of pre-stress. The construction of tensegrity structures is challenging due to its high sensitivity where its shape is unstable during construction. However, studies or literature on construction sequence of full scale tensegrity structures is relatively lacking. Hence, the study on application of form-finding results to the eventual construction of a tensegrity considering practical issues is needed. The focus of this study is irregular multi-layer prism tensegrity. A computational tool which uses a linear approach by combining length relation condition and force equilibrium equation is used in the form-finding process. The pre-stressing forces in the cables are applied based on the elongation of the cables. The construction sequence is investigated and improved through the erection of physical models. The effect of the construction sequence on the final configuration of the multi-layer prism tensegrity is studied. A detailed construction sequence of multi-layer prism tensegrity is proposed.
