Zusammenfassung Dieser Beitrag befasst sich mit der Anwendung des semi-probabilistischen Designkonzepts (Stufe I, DIN EN 1990) bei strukturellen Silikonklebstoffen. Zunächst werden Hintergrundinformationen zur Sicherheitstheorie und zum allgemeinen Rahmen des Eurocodes für die Herleitung von partiellen Materialsicherheitsbeiwerten gegeben. Dann wird im Rahmen dieses Beitrags ein konkreter Teilsicherheitsbeiwert für das Silikon „DOWSIL 993“ auf der Basis experimenteller Daten und einer neu vorgeschlagenen streckungsbasierten Grenzzustandsfunktion kalibriert. Dieser Teilsicherheitsbeiwert wurde dann für die Anwendung in Finite-Elemente-Berechnungsprogrammen derart erweitert, dass es nun zum ersten Mal möglich ist, diskretisierungsunabhängige statische Berechnungen von Silikon-Klebeverbindungen durchzuführen. Ein Beispiel für den statischen Nachweis einer geklebten Fassadenkonstruktion mittels Finite-Elemente-Berechnung zeigt die Anwendung von EC-0 auf Silikonklebstoffe und die Übertragung der EC-0-Methode auf die Finite-Elemente-Methode mit dem Ergebnis, dass netzunabhängige Traglasten ermittelt werden können.

Abstract This paper deals with the application of the semi-probabilistic design concept (level I, DIN EN 1990) to structural silicone adhesives in order to calibrate partial material safety factors for a stretch-based limit state equation. Based on the current legal situation for the application of structural sealants in façades, a new Eurocode-compliant design concept is introduced and compared to existing design codes (ETAG 002). This is followed by some background information on semi-probabilistic reliability modeling and the general framework of the Eurocode for the derivation of partial material safety factors at Level I. Within this paper, a specific partial material safety factor is derived for DOWSIL 993 silicone on the basis of experimental data. The data were then further evaluated under a stretch-based limit state function to obtain a partial material safety factor for that specific limit state function. This safety factor is then extended to the application in finite element calculation programs in such a way that it is possible for the first time to perform mesh-independent static calculations of silicone adhesive joints. This procedure thus allows for great optimization of structural sealant design with potentially high economical as well as sustainability benefits. An example for the static verification of a bonded façade construction by means of finite element calculation shows (i) the application of EC 0 to silicone adhesives and (ii) the transfer of the EC 0 method to the finite element method with the result that mesh-independent ultimate loads can be determined.

Ratu harbor beach is one of the mainstay tourist sites for the Regional Government of Sukabumi Regency in bringing PAD, besides public transportation facilities and terminals have a major role in supporting the queen port as a tourist attraction so that tourists are comfortable and facilitated in accessing through public transportation. The condition of the Pelabuhan Ratu Terminal, Sukabumi Regency is currently very poor, poorly maintained, and many supporting facilities are damaged and inadequate. This study aims to identify problems and formulate the type B terminal arrangement in Sukabumi Regency. The method used is descriptive qualitative in order to get a picture of the problems of the situation and conditions currently taking place or occurring in the present and the study of policies. Collecting data by field surveys, literature studies and interviews. The results in this study get a terminal B type terminal design concept Sukabumi Regency according to current and future needs.
