“…Combining a frame system and a shear wall system is appropriate for a multi-storey building with shear walls arranged around the lift shafts and stair wells. Both shear walls and frames participate in resisting the lateral loads resulting from earthquakes or wind or storms, and the portion of the forces resisted by each one depends on its rigidity, modulus of elasticity and its ductility, and the possibility to develop plastic hinges in its parts (Wang et al 2001;Islam et al 2012a, b;Balkaya, Kalkan 2003, 2004. Simulation-based assessment and multiple criteria assessment works on multi-storey buildings have been carried out by Jameel et al (2011) In structural modelling, it is required to consider the wall openings and slab opening since openings commonly exist in multi-storey buildings, for functional reasons (such as doors, windows, air ducts, etc.)…”

A multi-storey building is habitually modelled as a frame structure which neglects the shear wall/slab openings along with the inclusion of staircases. Furthermore, the structural strength provided by shear walls and slabs is not precisely incorporated. With increasing building height, the effect of lateral loads on a high-rise structure increases substantially. Inclusion of shear walls and slabs with the frame leads to improved lateral stiffness. Besides, their openings may play imperative role in the structural behaviour of such buildings. In this study, 61 multi-storey building configurations have been modelled. Corresponding analyses are performed to cope with the influence of shear walls, slabs, wall openings, masonry walls and staircases in addition to frame modelling. The finite element approach is used in modelling and analysis. Structural responses in each elemental combination are evaluated through equivalent static and free vibration analyses. The assessment reveals that inclusion of only slab components with frame modelling contributes trivial improvement on structural performance. Conversely, the presence of shear wall slabs with frame improves the performance noticeably. Increasing wall openings decreases the structural responses. Furthermore, it is not recommended to model staircases in addition to frame-slab-shear wall modelling, unless the effect of wall openings and slab openings is adequately considered.

“…Thus, tunnel form building provides better seismic performance in addition to their low construction cost as compared to the conventional RC buildings. This in turn makes them as an alternative buildings type to more base-isolated buildings [6].…”

The seismic performance of one-third scale double units three-storey tunnel form reinforced concrete building tied up with foundation beam tested under in-plane lateral cyclic loading are performed and analysed in this paper. This building is designed according to BS 8110, constructed in heavy structural laboratory and tested under in-plane lateral cyclic loading using displacement control method. The specimen is tested on a strong floor starting from 0.01% drift until 1.25% drift with an increment of 0.25% drift. From visual observation, the initial crack starts at +0.25% drift with more cracks observed at +1.0% drift. The ultimate lateral strength is reached at +1.25% drift and the experiemental work is stopped at this drift due to the danger of collapsing the tunnel form RC building. Based on the experimental hysteresis loops, the ultimate in-plane lateral strength is 93kN, maximum displacement ductility (  ) is 2.5, average elastic stiffness is 6.11kN/mm, average secant stiffness is 2.94 kN/mm and equivalent viscous damping (EVD) for the first cycle is 15% and second cycle is 6%. It can be concluded that this type of building will survive in a low to moderate earthquake but will collapse in a strong or severe earthquake due to the existence of a plastic hinge zone at wall-foundation interfaces.

“…Previous experimental studies conducted on shear-wall systems were generally limited to two-dimensional (2D) investigations. However, it was analytically proven that the 2D approach is not adequate to capture the important behavior of tunnel form buildings under seismic action due to significant slab-wall interaction and global tension-compression (T/C) coupling effects [2][3][4]. In addition, modern design guidelines for traditional RC buildings [5,6] are not adequate to account for interactions of thinner shear-wall and slab configurations as the common components of the tunnel form system.…”

The recent trend in the building industry of Turkey as well as in many European countries is towards utilizing the tunnel form (shear-wall dominant) construction system for development of multi-story residential units. The tunnel form buildings diverge from other conventional reinforced concrete (RC) buildings due to the lack of beams and columns in their structural integrity. The vertical load-carrying members of these buildings are the structural-walls only, and the floor system is a flat plate. Besides the constructive advantages, tunnel form buildings provide superior seismic performance compared to conventional RC frame and dual systems as observed during the recent devastating earthquakes in Turkey (1999 M w 7.4 Kocaeli, M w 7.2 Duzce, and 2004 M w 6.5 Bingol). With its proven earthquake performance, the tunnel form system is becoming the primary construction technique in many seismically active regions. In this study, a series of nonlinear analyses were conducted using finite element (FE) models to augment our understanding on their failure mechanism under lateral forces. In order to represent the nonlinear behavior adequately, The FE models were verified with the results of experimental studies performed on three dimensional (3D) scaled tunnel form building specimens. The results of this study indicate that the structural walls of tunnel form buildings may exhibit brittle flexural failure under lateral loading, if they are not properly reinforced. The global tension/compression couple triggers this failure mechanism by creating pure axial tension in the outermost shear-walls.
