AB  - The predominant form of damage observed during the February 2023 earthquakes in Turkey was the extensive failure of infill walls. This paper offers an insight into the repercussions of these earthquakes on infills, as well as their consequences for both the building inventory and the inhabitants. The unsatisfactory performance and significant destruction resulting from the interaction between flexible frames and rigid infill walls underscored the conceptual inadequacy of traditional infill systems (with mortar connections between frames and infills) in seismically active regions. Consequently, this paper proposes the isolation of infill walls as a viable solution to mitigate such devastating effects. This isolation system aims to offer designers, construction companies, and workers a functional and easily applicable solution. Full-scale experimental tests on isolated infilled RC frame specimens are presented, affirming the efficacy of the isolation system for infills with windows, doors, and full walls.

AB  - Reinforced concrete frames with masonry infill walls are popular form of construction all over the world as well in seismic regions. While severe earthquakes can cause high level of damage of both reinforced concrete and masonry infills, earthquakes of lower to medium intensity sometimes can cause significant level of damage of masonry infill walls. Especially important is the level of damage of face loaded infill masonry walls (out-of-plane direction) as out-of-plane load cannot only bring high level of damage to the wall, it can also be life-threating for the people near the wall. The response in out-of-plane direction directly depends on the prior in-plane damage, as previous investigation shown that it decreases resistance capacity of the infills. Behaviour of infill masonry walls with and without prior in-plane load is investigated in the experimental campaign and the results are presented in this paper. These results are later compared with analytical approaches for the out-of-plane resistance from the literature. Conclusions based on the experimental campaign on the influence of prior in-plane damage on the out-of-plane response of infill walls are compared with the conclusions from other authors who investigated the same problematic.

AB  - Reinforced concrete (RC) buildings with masonry infill walls are widely used in many countries all over the world. Although infills are considered as non-structural elements, they significantly change dynamic characte-ristics of RC frame structures during earthquake excitation. Recently, significant effort was spent on studying decoupled infills, which are isolated from the surrounding frame usually by adding a gap between frame and infill. In this case, the frame deformation does not activate infill wall, thus infills are not influencing the behaviour of the frame. This paper presents the results of the investigation of the behaviour of RC frame buildings with the INODIS system that decouples masonry infills from the surrounding frame. Effect of masonry infill decoupling was investigated first on the one-bay one-storey frame. This was used as a base for parametric study on the frames with more bays and storeys, as well as on the building level. Change of stiffness and dynamic characteristics was analysed as well as response under earthquake loading. Comparison with the bare frame and traditionally infilled frame was performed. The results show that behaviour of the decoupled infilled frames is similar to the bare frame, whereas behaviour of frames with traditional infills is significantly different and demands complex numerical models. This means that if adequate decoupling is applied, design of infilled frame buildings can be significantly simplified.

AB  - The use of masonry infill walls in RC frame structures is common in many countries, even in seismically active areas, where the observations made after strong earthquakes have shown that masonry infills significantly modify the dynamic behaviour of the structure, thus causing total collapses of buildings and loss of human lives. The innovative system called Innovative Decoupled Infill System (INODIS) was developed with the aim to improve the behaviour of infilled RC frames by decoupling the frame and the masonry infill. Description of the system with the installation steps is given with the experimental tests showing that INODIS system highly reduces the activation of infills, thus enables reaching high in-plane drifts without having any damage and at the same time provides stable and reliable connection in out-of-plane direction. Also, the micro model showed that INODIS system improves the behaviour of AAC masonry infills by reducing the level of damage in the walls and postponing infill activation to higher drift levels.

AB  - It is well known that seismically loaded reinforced concrete frames with masonry infills exhibit an unfavourable behaviour which can lead to serious damages of the masonry infill panels and the surrounding reinforced concrete frame. Especially recent earthquakes clearly showed the low seismic resistance with serious consequences for the occupants of affected buildings. This is astonishing at first glance, since numerous experimental investigations and numerical simulations have been carried out to study the seismic behaviour of reinforced concrete frames with masonry infills. The results of the fundamental research served as a basis for the derivation of simplified seismic design approaches, which consider the seismic actions in-plane and out-of-plane as a separate design problem. Although the necessity of considering the interaction has already been pointed out by some authors, there is no applicable design concept for the engineering practise available. Within the framework of the joint European project INSYSME, comprehensive experimental test campaigns were carried out on reinforced concrete frames with masonry infills. The tests include separate in- and out-of-plane loading, sequential in- and out-of-plane loading and simultaneous in- and out-of-plane loading conditions. The experimental results lead to significantly lower resistances for sequentially applied loading and to rigorous reductions of the seismic resistance if the loads are applied simultaneously. The results show clearly, that the existing design concepts are insufficient and definitely not on the safe side. This article presents and discusses the main findings of the tests results and further simulation results.

AB  - Severe damages of masonry infill walls in reinforced concrete and steel frames have been observed after many earthquakes. Typically, masonry infill walls are loaded not just in-plane and out-of-plane but also simultaneously in both directions. While the damage due to the in-plane loading is caused by the increase of interstory drift, out-of-plane collapse is induced by high inertia forces perpendicular to the wall. In reality, both effects strongly interact with each other leading to a further reduction of deformation and strength capacity of the masonry infill. Within the project INSYSME the authors proposed the new system INODIS which decouples the frame and the masonry infill by means of specially shaped rubbers placed in between frame and infill. The decoupling reduces the damages and the infill behaves like a real non-structural element. At the same time the special shape of rubber connection prevent an out-of-plane failure of the infill wall. A series of full scale tests on RC frames with clay brick masonry infills have been carried out in order to validate the efficiency of the system. The experimental tests were carried out separately for in-plane and out-of-plane loading as well as simultaneously applied loads in both directions using a special experimental set-up with airbags. Furthermore small specimen tests were carried out to check material characteristics of the components and the resistances of the connections. The experimental results are used as a basis for the validation of the numerical models, developed on micro and macro level. These models can be used for parametric studies to derive simple design rules for everyday practice.

AB  - Masonry is a widely spread construction type which is used all over the world for different types of structures. Due to its simple and cheap construction, it is used as non-structural as well as structural element. In frame structures, such as reinforced concrete frames, masonry may be used as infill. While the bare frame itself is able to carry the loads when it comes to seismic events, the infilled frame is not able to warp freely due to the constrained movement. This restraint results in a complex interaction between the infill and the surrounding frame, which may lead to severe damage to the infill as well as the surrounding frame. The interaction is studied in different projects and effective approaches for the description of the behavior are still lacking. Experimental programs are usually quite expensive, while numerical models, once validated, do offer an efficient approach for the investigation of the interaction when horizontally loaded. In order to study the numerous parameters influencing the seismic load bearing behavior, numerical models may be used. Therefore, this contribution presents a numerical approach for the simulation of infill masonry in reinforced concrete frames. Both parts, the surrounding frame as well as the infill are represented by micro modelling approaches to correctly take into account the different types of failure. The adopted numerical model describes the inelastic behavior of the system, as indicated by the obtained results of the overall structural response as well as the formation of damage in the infilled wall. Comparison of the numerical and experimental results highlights the valuable contribution of numerical simulations in the study and design of infilled frames. As damage of the infill masonry may occur in-plane due to the interaction as well as out-of-plane due to the low vertical load, both directions of loading are investigated.

abstract = "Masonry is a widely spread construction type which is used all over the world for different types of structures. Due to its simple and cheap construction, it is used as non-structural as well as structural element. In frame structures, such as reinforced concrete frames, masonry may be used as infill. While the bare frame itself is able to carry the loads when it comes to seismic events, the infilled frame is not able to warp freely due to the constrained movement. This restraint results in a complex interaction between the infill and the surrounding frame, which may lead to severe damage to the infill as well as the surrounding frame. The interaction is studied in different projects and effective approaches for the description of the behavior are still lacking.
