Damage Control ◽

Non Linear

Tanah khusus merupakan profil lapisan tanah yang rawan dan berpotensi gagal atau runtuh akibat beban gempa seperti mudah likuifaksi, lempung sangat sensitif, tanah tersementasi lemah, dan lempung sangat organik yang membutuhkan investigasi geoteknik spesifik dan analisis respons spesifik-situs. Salah satu faktor yang mempengaruhi perencanaan struktur bangunan tahan gempa adalah kondisi lapisan tanah dan bentuk konfigurasi dari struktur yang dianalisis. Penelitian ini bertujuan untuk mengevaluasi kinerja struktur bangunan beton bertulang di tanah khusus dengan menggunakan metode analisis pushover. Analisis pushover adalah metode statis non-linear dimana struktur mengalami pembebanan gravitasi dan pola beban lateral yang dikendalikan perpindahan monotonic yang terus meningkat melalui perilaku elastik dan inelastik hingga kondisi akhir tercapai. Hasil penelitian menunjukan bahwa tingkat kinerja struktur analisis pushover berdasarkan ATC-40 struktur termasuk dalam level kategori Damage Control.

Empirical Methodology

An empirical methodology to evaluate damage by the use of two damage indicators for 2D steel/concrete composite structures is proposed. This methodology has been established with aid of the results of an extensive parametric study regarding the non-linear behaviour of 48 steel/concrete composite frames subjected to 100 far-fault records. A large number of inelastic dynamic analyses are conducted by increasing the earthquake motions to lead the frames to several levels of non-linear response. The results of the analyses show that the characteristics of the structure and the ground motions affect damage of the structures. The results are post-processed by the use of statistical methods to generate expressions, which show the effect of the abovementioned parameters and give an evaluation of the damage indicators utilised here. In particular, given the characteristics of the frames and the record, someone can compute the maximum damage found in beams and columns. Finally, one example serves to show the use of the developed formulae and demonstrates their validity.

Control Application

For the design and construction of buildings in seismic areas the European Standard EN 1998-1:2004 offers two non-linear methods, namely: a non-linear pushover based static method and a nonlineardynamic method. This paper discusses those methods which differ from one another in respectto accuracy, simplicity and transparency. Non-linear static procedures were developed in the worldwith the aim of overcoming the insufficiency and limitations of linear methods, whilst at the sametime maintaining a relatively simple application. All procedures incorporate performance-basedconcepts paying more attention to damage control. Application of the presented procedures isillustrated by means of an example of an eight-story reinforced concrete frame building.

Preceding Session

(Ed. note: The custom in these Symposia has been to have a summary-introductory presentation which lasts about 1 to 1.5 hours, during which discussion from the floor is minor and usually directed at technical clarification. The remainder of the session is then devoted to discussion of the whole subject, oriented around the summary-introduction. The preceding session, I-A, at Nice, followed this pattern. Christy suggested that we might experiment in his presentation with a much more informal approach, allowing considerable discussion of the points raised in the summary-introduction during its presentation, with perhaps the entire morning spent in this way, reserving the afternoon session for discussion only. At Varenna, in the Fourth Symposium, several of the summaryintroductory papers presented from the astronomical viewpoint had been so full of concepts unfamiliar to a number of the aerodynamicists-physicists present, that a major part of the following discussion session had been devoted to simply clarifying concepts and then repeating a considerable amount of what had been summarized. So, always looking for alternatives which help to increase the understanding between the different disciplines by introducing clarification of concept as expeditiously as possible, we tried Christy's suggestion. Thus you will find the pattern of the following different from that in session I-A. I am much indebted to Christy for extensive collaboration in editing the resulting combined presentation and discussion. As always, however, I have taken upon myself the responsibility for the final editing, and so all shortcomings are on my head.)
