Fire risk analysis in urban areas is a critical component of planning and safety management. It involves assessing the likelihood fires occurring potential impact those on people, property, environment. First step identification fire hazard. This sources ignition fuel sources. Next assessment vulnerable assets. Urban contain various assets that may be to fire, including residential buildings, commercial properties, industrial facilities, transportation infrastructure, facilities such as...

Numerical approach using finite element method has been used to evaluate the behaviour of reinforced concrete frame structure subjected fire. The is previously designed in accordance with Eurocode standards for design structures earthquake resistance, ductility class M. Thermal and structural response are obtained a commercially available software ANSYS. Temperature-dependent nonlinear thermal mechanical properties adopted according standards, application constitutive model triaxial...

Improper execution of bonding FRP plates to the RC beam can result into appearance zones where bond is substantially weaker, and air pockets are present. This paper presents an attempt model weak zone its influence on global response externally CFRP strengthened beam. A numerical displacement-based fibber was used for prediction beams with CFRP. Also, using concepts artificial neural networks results performed analyses, another has been made. Both models generated excellent some them will be...

Artificial neural networks, in interaction with fuzzy logic, genetic algorithms, and represent an example of a modern interdisciplinary field, especially when it comes to solving certain types engineering problems that could not be solved using traditional modeling methods statistical methods. They trend practical developments within the prognostic field and, acceptable limitations, enjoy generally recognized perspective for application construction. Results obtained from numerical analysis,...

Understanding the performance and response of frame structures in fire is a particular importance for structural design. The specialized computer program SAFIR enables analysis different types structures, constructed with materials. options are presented on eight scenarios standard exposure three bay two story reinforced concrete frame. results the: temperature distribution within elements, resistance whole structure, bending moments deformations elements discussed. worst scenario defined....

The non uniform temperature fields in the cross section of structural elements exposed to fire cause thermal dilatations which induce internal forces. In same time changes longitudinal elongations and if these are restricted, additional axial stresses will be induced. this case various support conditions can have a significant influence on resistance reinforced concrete elements. paper three different as: pin-pin, pin-fixed fully fixed were used model RC beams with level restraint. ISO-fire...

This paper presents a fire resistance analysis of two-way reinforced concrete (RC) slabs. The study analyzes the effect specific parameters—concrete cover thickness, span, and support conditions—on To that end, slabs were exposed to Standard Fire ISO 834, 3D nonlinear numerical analyses conducted in SAFIR2016. results evaluated against experimental reported literature. agreement between two sets was satisfactory throughout test. Nonetheless, verify obtained results, all testing-related...

Fire following an earthquake is important factor causing damage to buildings and life-line structures. Therefore, besides satisfying structural design requirements for normal loads, such as dead live loads including the seismic hazard, should also be designed withstand fire earthquakes a certain minimum duration required desired level of performance. The behavior particular reinforced concrete structure that was exposed after action presented in this paper. response evaluated using pushover...
