This paper presents the results of a study of short-term rheological strain increments in a push-out test for double-lap glued joints. A total of 15 specimens consisting of cross laminated timber (CLT) elements and precast concrete slabs were tested. The joint between the elements was made as a glued joint using innovative 3 mm thick prefabricated...

As long-term investigations are often too time- and cost-consuming, short-term experiments are introduced for investigating the behaviour of connections in timber-concrete-composite elements. The paper proposes short-term double shear tests with adhesive and mechanical connections to investigate their time-dependent behaviour. The proposed evaluati...

Timber-Concrete-Composites (TCC) are a perfect symbiosis of two entirely different building materials, as the most favourable properties of both components are utilized. This ensures the efficient use of natural resources. As regards the long-term creep behaviour however, only a rough estimation can be done based on the current versions of the desi...

Material properties of wood under compression perpendicular to the grain and rolling shear are important for the engineering design of timber structures. This regards the short-term stiffness and strength, their dependence on the moisture content of wood, as well as the time-dependent behavior. Norway spruce clear wood properties in the transverse...

Cross-laminated timber (CLT) slabs in residential buildings need additional weight, e.g., in the form of screeds or gravel layers, to fulfill the criterion for the highest impact-sound class. The additional mass is, however, not exploited for the load bearing behavior, but adds additional weight and leads to an increased height of the floor constru...

This review of the added value of multi-scale modeling of concrete is based on three representative examples. The first one is concerned with the analysis of experimental data, taken from four high-dynamic tests. The structural nature of the high-dynamic strength increase can be explained by using a multi-scale model. It accounts for the microstruc...

This contribution deals with an assessment of the added value resulting from the use of a multiscale model of concrete as the basis for structural analysis of a segmental tunnel ring. The assessment rests on the comparison of a triad of results. They are obtained from a real-scale test of a segmental tunnel ring, from conventional structural analys...

In this paper, the significance of application-oriented fundamental research on concrete and reinforced concrete structures for progress regarding practical applications to structural design is addressed based on four examples. They were treated in a joint research project of Vienna University of Technology and Tongji University. The first topic re...

The strength of specimens made of cementitious materials increases with increasing loading rate. Herein, the model of Fischer et al. (CCR 58, 2014, 186–200) is revisited in the context of high-dynamic compression and extended to high-dynamic tension. The model is based on the assumptions (i) that cracking will start if the quasi-static material str...

Six different concretes are characterized during material ages between 1 and 28 days. Standard tests regarding strength and stiffness are performed 1, 3, 7, 14, and 28 days after production. Innovative three-minute-long creep tests are repeated hourly during material ages between one and seven days. The results from the standard tests are used to a...

The Hong Kong-Zhuhai-Macao-Bridge (HZMB) is a traffic link consisting of two parts connected by an immersed tunnel. The structure may be subjected to moderate earthquakes. During such an exceptional load case, the joints between the 33 tunnel elements must remain water-tight. This was the motivation to perform 44 earthquake tests of 13 scaled eleme...

This paper contains an assessment of the added value of multiscale material models for concrete in the context of macroscopic structural analysis of (steel-reinforced) concrete structures. Two examples are discussed. They are inspired by the possibility of car accidents inside the immersed tunnel of the Hong Kong-Zhuhai-Macao Bridge (HZMB). The fir...

The title of this work represents a figurative counterpart of bridging the topographical gap between Hongkong and Macao. Presently under construction, the bridge that connects these two cities at opposite sides of the mouth of the Pearl River is interrupted by a submersed tunnel, which is the actual research object of this paper. By means of four d...

The topical ambiguity of the term “bridging the gap” manifests itself in the 35.6 km long Hongkong-Zhuhai-Macao Bridge, presently under construction, and in multiscale analysis of a 5.7 km long tunnel below the bottom of the South China Sea, interrupting the bridge for shipping. On the one hand, a topographical gap is being bridged while, on the ot...
