“…This procedure can be performed with the support of databases with browser-based interphases in substitution of traditional paperbased data collecting-for example, the implementation of the Rapid Visual Screening for reinforced-concrete constructions [10]. The implementation of this method with the support of remote inspections was explored for the city of George Town (Malaysia), finding an encouraging potential on this workflow [11].…”

European countries are affected by various levels of seismic hazard, including many areas with medium to high seismicity. Heavy damage over large areas has been observed in past earthquakes in these countries, particularly in masonry buildings located in historical centers, confirming the need for enhancing the current knowledge on the seismic vulnerability of these constructions, so more informed technical and political decisions towards the mitigation of the risk can be taken. However, the characterization of building stocks for engineering purposes is still an open issue due to the enormous amount of resources that such a project would require. Nevertheless, the availability of virtual images and maps represents an outstanding opportunity for having remote approaches to urban environments. The role of on-site inspections can be complemented or even substituted by means of these remote approaches, provided it is complemented with suitable approaches. The use of these resources is not new, but the critical assessment of their capabilities and limitations deserves a critical discussion. The present paper aims at assessing the opportunities offered by web-based mapping platforms in the context of seismic vulnerability assessment of masonry buildings in old urban areas. After evaluating the advantages and shortcomings of some of the most popular web-based mapping services, an explanatory application to a set of 39 buildings located in the historic center of the city of Leiria (Portugal) is presented and critically discussed, contrasting the results obtained by using on-site and remote inspections. Two different seismic vulnerability assessment approaches are applied and analyzed herein, confirming that web-based mapping platforms can represent an efficient and cost-effective complement to traditional field surveys when the large-scale seismic vulnerability of old urban areas is of interest.

Every structure necessitates a table to live a system of battling highest forces caused by wind speed or heavy earthquakes. One of the premium preparations has to share the representation of structural elements that holds the arrangement of earthquake loads together. When the trouble of the tallness of the structure is superior than before they turn out to be greater as well as the addition of tempting additions to oppose systems such as truss contains of shear wall is essential. If the live load present in the structure has more, the reduction in the failure of the structural elements will be the main criteria before construction. In this work, some of the studies has presented in which they have introduced different live loadings in multi-storeyed building with seismic loading. Results concluded that it is necessary to perform the live load with highest importance factor as per seismic codal provisions.

“…Even though the URM buildings in Malaysia are designed according to the Malaysia Standard (MS), there were few research published in timber engineering, especially timber strengthening (Kassem et al, 2021). This statement is supported by Abd Malek et al (2016), who stated that due to a lack of information on tropical timber connections, it was difficult to design or choose the suitable species of timber or its connections that fit the required purpose and ensure its performance.…”

This study is done to evaluate the structural performances of bolted timber connections in local hardwoods. In Sarawak, Belian hardwood is typically used to construct the floor and wall diaphragm for unreinforced masonry (URM) buildings. Unfortunately, there is a lack of experimental data on bolted connection of Belian hardwoods. This gap in experimental data might lead to difficulties in designing bolted timber connections for strengthening purposes. Therefore, the study was carried out to evaluate the existing equations in predicting the bolted connection in Belian hardwood. A calibration factor for Belian hardwood will be provided to optimise the use of the current design equation in predicting the row shear failure mode. The European Yield Model (EYM) and Malaysia Standard (MS) will also be compared to the experimental results to verify the suitable equation to predict the strength of the ductile mode of failure. From the comparison between experimental versus prediction values, EYM and Row Shear equation were acceptable to predict the bearing and row shear failure while the MS was found too conservative with a range from 0.16 to 0.25 compared to the 5th percentile experimental results.
