The distribution of stiffness, strength, and mass in both vertical horizontal orientations affects how well a high rise structure performs during powerful earthquake events. A building is considered irregular if there difference between the adjoining storeys. performance behavior regular G+10 reinforced concrete (RC) buildings under seismic loading are main topics current study. In this study, ...

In the last decades, need to develop new enhanced typologies of steel reinforcement bars with improved ductility and durability performance in presence aggressive environmental conditions progressively increased due negative consequences that corrosion showed on structural capacity reinforced concrete (RC) buildings. Within recently concluded NEWREBAR research project, a reinforcing grade Dual-...

This work presents an efficient approach using time-varying autoregressive with exogenous input (TVARX) model and a substructure technique to identify the instantaneous modal parameters of a linear timevarying structure and its substructures. The identified instantaneous natural frequencies can be used to identify earthquake damage to a building, including the specific floors that are damaged. ...

In the past few decades, tall buildings of 30 to over 100 storeys are becoming more common in modern cities around the world, especially in Asia and the Middle East, according to the Council on Tall Buildings and Urban Habitat. Extensive research has focused on the technical aspects of erecting tall buildings, yet few recent studies have been conducted to examine occupants’ experiences and resp...

Plastic PicoRad detectors with activated charcoal have been used for radon monitoring in local kindergartens and schools in two cities, Kalisz and Ostrów Wielkopolski, in the region of Greater Poland. Detectors were exposed for a standard time of 48 h during the autumn and winter of 2011 in 103 rooms (Kalisz) and 55 rooms (Ostrów Wlkp), respectively. The detectors were calibrated in the certifi...

The objective of the “Tree Extraction” project organized by EuroSDR (European Spatial data Research) and ISPRS (International Society of Photogrammetry and Remote Sensing) was to evaluate the quality, accuracy, and feasibility of automatic tree extraction methods, mainly based on laser scanner data. In the final report of the project, Kaartinen and Hyyppä (2008) reported a high variation in the...

Earth building materials offer architects, engineers and clients a low carbon walling solution for rise properties (under 3 storeys). Unfortunately, the mixture of sub-soil fibre known as Cob does not currently comply with thermal aspects many regulations across world. This paper designs optimises low-density cob mix intended to maintain material’s credentials whilst conforming regulations. Sam...

The worldwide dissemination of the pilotis multi-storey RC buildings, generally attributed to architect Le Corbusier, was contemporary with a structural engineering line thought that advocated soft first storey as means filtering down seismic inertia forces in upper storeys. These two architectural and international trends, combined outdated detailing low-code design, greatly increase risks dev...

This paper investigates the role of sheathing-to-framing connection ductility in evaluation structural q-behaviour factor for Light-Frame Timber (LFT) buildings, by means Incremental Dynamic Analyses (IDA). approach allows to consider nonlinear cyclic behaviour walls, which cannot be taken into account with sta...
