The provisions of Amendment No. 1 to DBN V.1.-1-12: 2014 «Construction in seismic regions of Ukraine» [1] are presented. The norms take into account the experience and modern trends of buildings and structures design in seismic regions with intensities of 6 to 10 points according to DSTU B.1.1-28:2010 «Scale of seismic intensity» [6] and DSTU-N B EN 1998-1:2010 «Eurocode 8. Design of structures for earthquake resistance - Part 1: General rules, seismic actions and rules for buildings (EN 1998-1:2004, IDT)» [4]. In Amendment No.1 to DBN V.1.-1-12:2014 the requirements are given as to the use of the maps of general seismic zoning (GSZ-2004) of the territory of Ukraine, in particular GSZ-2004-C map, when designing the objects of significant CC3 consequences (importance) class for residential and public buildings, which are not identified as the highly hazardous objects in compliance with the law of Ukraine «On objects of higher risk».The experimental and theoretical researches conducted at the NIISK during 2015-2017 have allowed the development of requirements for determining the seismic loads on the multistory and high-rise (with heights of 73.5 m and more) buildings, as well as of recommendations for designing the low-rise (up to 3 storeys) buildings with the bearing walls of autoclaved aerated concrete blocks according to the design building site seismicity (6, 7 and 8 points).The requirements are formulated as to the use of aerated concrete blocks with the characteristics of D 400 C 2.5 and D 300 C 2.0 (average density and compressive strength); allowable values of floor skewing in lowrise buildings with cellular concrete bearing walls for three levels of earthquakes (SZ – weak earthquake, PZ – design earthquake and MDE – maximum design earthquake); the coefficient k1, which takes into account the structures inelastic deformations and local damages at the earthquakes. |
