A simple method for the non-linear static analysis of complex building structures subjected to monotonically increasing horizontal loading (push-over analysis) is presented. The designed be a part new methodologies seismic design and evaluation structures. It based on extension pseudo-three-dimensional mathematical model structure into range. consists planar macroelements. For each macroelement, bilinear or multilinear base shear–top displacement relationship assumed. By step-by-step an...

This study presents an integrated approach to seismic assessment and retrofitting of multi-residential masonry buildings constructed between 1945 1963 in urban centers across former Yugoslavia, focusing on Ljubljana, Slovenia. These buildings, characterized by unreinforced walls prefabricated floor slabs, represent a significant portion the housing stock are highly vulnerable loading. Building previous research, this paper develops standardized typology classification conducts detailed...

Abstract The paper summarizes the results of laboratory tests that were performed on samples extruded polystyrene foam (XPS). aim investigation was to determine mechanical characteristics which are essential for seismic analysis modern low-energy building structures, where XPS boards used as a thermal insulation layer beneath building's foundations. As well this, shear behaviour differently composed (TI) foundation sets investigated, and their friction capacity estimated. showed that, in...

Abstract In the paper a simplified nonlinear method has been applied to analysis of base‐isolated structures. first part, three‐linear idealization capacity curve is proposed. The initial stiffness defined based on yielding point in superstructure, whereas secondary slope depends failure mechanism superstructure. A consequence much more pronounced slope, which does not correspond presumptions used originally proposed N2 method. parametric dynamic study single degree freedom systems with...

Urban system is a complex mix of interdependent components and dynamic interactions between them that enable it to function effectively. Resilience urban indicates the ability resist, absorb, accommodate recover from effects hazard in timely efficient manner. In relevant literature, most studies consider individual separately. On other hand, purpose this paper assess as whole, considering all their interactions. The goal study possibilities for holistic evaluation resilience natural...

The seismic retrofitting measures which are appropriate for buildings belonging to the architectural heritage limited, since extent such allowed be altered is severely limited. In paper possibilities exist implementation of base isolation in case upgrade unreinforced masonry (URM) structures valuable have been investigated. A new methodology modeling URM buildings, based on an equivalent frame model with plastic hinges, was used this purpose. study involving a typical neo‐renaissance...

Abstract The paper deals with the applicability of extended N2 method to base‐isolated plan‐asymmetric building structures. results obtained by usual pushover analysis a 3D structural model are further combined aid linear dynamic (spectral) account for effects caused asymmetry. In paper, has been applied seismic mass‐eccentric four‐storeyed RC frame isolated lead rubber bearings. Three different positions center isolation system (CI) respect mass (CM) and stiffness superstructure (CS) were...

Historic masonry buildings often require structural repair or retrofit to attain a satisfactory level of seismic resistance. This paper analyses the effect externally bonded fibre-reinforced polymer (FRP) retrofitting systems on global response such in order achieve fundamental code-based requirements that refer structure's state damage for specified limit state. As case study, three-storey historic unreinforced (URM) building was selected. The first part presents an FRP design procedure...

The paper examines the seismic response of an existing externally braced steel frame high-rack structure and analyses effects mass eccentricities that can be realistically achieved by asymmetric positioning stored payload. Apart from symmetric, three different extreme payload distributions with varying occupancy levels have been considered, concentrated: (i) at topmost part structure, (ii) upper corner (iii) outermost edge structure. performance has analysed using unidirectional non-linear...

Seismic behaviour of buildings founded on thermal insulation layerThermal under the building foundation plate or strip foundations prevents bridge contact between and supporting terrain reduces energy consumption in modern passive low houses.In paper seismic with different heights, floor plan dimensions, soil conditions layers have been analysed.The results simplified analyses shown, that potentially negative influences inserting could be expected only for more than two three storeys.

According to the new directives about rational and efficient use of energy, thermal bridges in buildings have be avoided, insulation (TI) layer should run without interruptions all around building - even under its foundations. The paper deals with seismic response multi-storeyed reinforced concrete (RC) frame structures founded on an extruded polystyrene (XPS) placed beneath foundation slab. purpose is elucidate problem a TI from resistance point view, assess behaviour such buildings, search...

Recently, an increasing trend of passive and low-energy buildings transferring from non earthquake-prone to regions has thrown out the question about seismic safety such buildings. The paper describes most commonly used details energy efficient construction, which could be critical point view earthquake resistance. focuses on prevention ground floor slab thermal bridge presents a case study response multi-storey wooden founded RC foundation lying insulation (TI) layer made extruded...

The paper assesses the earthquake vulnerability of multi-residential buildings in Slovenia, although it is limited to that were built before 1981, time when building codes much less elaborated than today. In paper, based on completion year, are classified into different periods, which characterized by important historical events and bigger changes codes. assessment data from number storeys, prevailing structural material year last renovation as obtained census population, households...
