Failure of some elements in the structure can play triggering role for beginning of collapse progression. The critical element is the structural element that when it fails, leads to progressive collapse. To find the critical element of the structure, sensitivity analysis should be done. But there are not specific structural criteria for using in sensitivity analysis. In this paper following GSA, UFC 4-023-03 and ASCE guidelines, sensitivity analysis has been modified and applied to find the critical element of a major number of reinforced concrete structures. 1080 3D nonlinear pushdown analyses were done and the results showed that the place of the critical elements differs in different stories and different plan shapes of high rise structures. In the structures with high aspect ratio in height, the critical element of the whole structure is located in the story of 2/3 height of the structure. When the aspect ratio of the structure in plan increases, sensitivity of the columns in the long dimension of the structure become closer to each other.

As the population growth and land resources declining, high-rise building project is increasingly common in the construction work. Through in-depth thinking and active exploration, specific attention to matters of deep foundation pit and pile foundation construction technique, which is the key construction techniques in the high-rise building project, was summarized in this article. It suggests to make a careful and detailed geological survey, and then choose the right design program and develop a reliable construction plans. This scheme was proved to be a useful reference and guidance for the development of high-rise building construction technology.

Problematic issues of construction of pile-foundation slab of high-rise residential building in the area of underground mining (underground mining with general under working area 25%; the fissured limestone may collapse under the weight of the building) are systematized. The experience of modeling by method of ultimate elements of pile-foundation slab of three-section residential building in the area of underground mining and results of the geodesic monitoring of complex building are presented.

Kesuksesan suatu proyek merupakan hal yang ingin dicapai oleh seluruh pihak yang terlibat di dalamnya. Inefisiensi struktur yang terdapat dalam suatu proyek dapat menghalangi pencapaian kesuksesan yang diharapkan dalam suatu proyek. Oleh karena itu, diperlukan suatu teknik yang dapat menanggulangi permasalahan tersebut. Salah satu teknik yang dapat digunakan adalah value engineering. Dalam beberapa studi, telah dilakukan modifikasi pada analisis teknik value engineering. Salah satu modifikasi yang dimaksud adalah dengan menerapkan teknik TRIZ. Penerapan teknik TRIZ dalam analisis value engineering diyakini dapat memberikan kemudahan dalam menemukan solusi dalam permasalahan yang dihadapi. Struktur pondasi suatu proyek high rise building akan dijadikan objek studi. Studi ini bertujuan untuk menemukan sistem pondasi yang dapat diterapkan pada objek studi. Teknik TRIZ yang dilakukan dalam studi ini hanya diterapkan dalam fase kreatif yang terdapat di dalam analisis value engineering. Sistem awal pondasi yang diterapkan dalam objek studi adalah sistem bored pile foundation. Sistem bored pile foundation memiliki total biaya pelaksanaan sebesar Rp 18.719.136.609,24, penurunan rata-rata sebesar 48,24 cm, waktu pelaksanaan selama 92 hari, dan skor penilaian sebesar 122,92. Penerapan teknik TRIZ dalam analisis value engineering memberikan dua buah alternatif, yaitu sistem raft foundation dan raft-pile foundation. Evaluasi yang dilakukan terhadap ketiga sistem yang dianalisis memberikan hasil bahwa sistem raft-pile foundation memberikan hasil yang paling baik dengan total biaya pelaksanaan sebesar Rp 15.910.991.105,30, penurunan rata-rata sebesar 14,17 cm, waktu pelaksanaan selama 87 hari, dan skor penilaian sebesar 144,58. Sistem raft-pile foundation memberikan penghematan biaya sebesar 15% terhadap sistem bored pile foundation.The success of a project is something that all parties involved in it want to achieve. The structure inefficiency found in a project can hinder the achievement of expected success in a project. Therefore, we need a technique that can overcome these problems. One technique that can be used is value engineering. In several studies, modifications have been made to the analysis of value engineering techniques. One modification is meant by applying the TRIZ technique. The application of TRIZ techniques in value engineering analysis is believed to provide convenience in finding solutions to the problems encountered. The foundation structure of a high rise building project will be the object of study. This study aims to find a foundation system that can be applied to the object of study. The TRIZ technique used in this study is only applied in the creative phase contained in the value engineering analysis. The initial foundation system applied in the object of study is the bored pile foundation system. The bored pile foundation system has a total implementation cost of Rp. 18,719,136,609.24, an average reduction of 48.24 cm, an implementation time of 92 days, and an assessment score of 122.92. The application of the TRIZ technique in value engineering analysis provides two alternatives, namely the raft foundation system and the raft-pile foundation. Evaluations conducted on the three systems analyzed give the result that the raft-pile foundation system provides the best results with a total implementation cost of Rp. 15,910,991,105.30, an average decrease of 14.17 cm, an implementation time of 87 days, and assessment score of 144.58. The raft-pile foundation system provides a cost savings of 15% over the bored pile foundation system.
