The mechanical behavior of T-stubs bolted connection with two and four bolts per row under monotonic cyclic loading is analyzed in this paper using a 3D finite element model. aim the model that takes into account material geometrical nonlinearities to obtain evolution prying forces throughout cycles loading. numerical also used compare those row. results are prepared be as basis for proposing a...

Steel frames equipped with chevron bracing (?-CBF) are usually less ductile than other steel systems. Therefore, in many cases, it can be convenient to design ?-CBF exploit their stiffness and resistance enforce a pseudo-elastic seismic response of the building low moderate zones. In current EC8, rules for same as those high frames, thus potentially leading massive, over-resistant uneconomic ne...

The present study proposes a new method to predict the ultimate load bearing capacity of structural notched beams subjected splitting. Reinforced and unreinforced cases are investigated by using FE-model for splitting failure. contribution mode I II in crack extension mechanisms is implemented numerical model considering mixed criterion established on R-curves wood. influences notch reinforceme...

The production and processing of building materials is responsible for a significant share global greenhouse gas emissions. Nevertheless, in current practice, lot material wasted, because load-bearing structures are often grossly overdimensioned. Numerical optimization tools have the potential to reduce consumption structural materials, but lack customized algorithms prohibits their use daily d...

Monitoring was conducted for the structural steel types used in Republic of Kazakhstan construction buildings using metal frames. For each type it first time determined hardness specification by Brinell methods. Hardness is applied to determine yield strength, breaking strength and relative deformation at rupture. These parameters are considered compliance with requirements National Annex Euroc...

Abstract We present updated seismic hazard maps for the United Kingdom (UK) intended use with National Annex revised edition of Eurocode 8. The last national UK were produced by Musson and Sargeant (Eurocode 8 zoning UK. British Geological Survey Report CR/07/125, Kingdom, 2007). model uses an up-to-date earthquake catalogue Isles, which completeness periods have been reassessed, a modified sou...
