Modern design trends of structures aim to protect the
\nfacades, finishing, equipment integrated in buildings as well as reducing
\nplastic deformations (remanent). These objectives come from operational considerations of
\nthe building following a seismic event, protection of the investment of
\nwhich a significant percentage results from building fa\u00e7ade and partitions, finishes and technical and technological equipment of
\nthe building, as well as reducing the commissioning costs after a seismic event.
\nTransposing these issues into design requirements necessitates, in the case of the conventional structure design approach,
\nconsiderations of low behavior factor in order to
\nminimize the level of degradation of the respective structure
\nand to minimize the plastic deformations in the structural elements. The deformations of the structural elements are transposed into
\ndeformations of all the systems connected to the structural system.
\nThe alternative involves the consideration of a base isolation system of the building which effectively solves
\nthe aforementioned desideratum, but which involves a calibration of the solution with nonlinear dynamic analyses
\nusing real and\/or synthetic accelerograms.
\nIt is thus up to the structural engineer to choose the sets of artificial accelerograms
\ngenerated from the design response spectrum or scaled for compatibility with the design
\nspectrum.
\nThe purpose of the article is to present some methods of scaling of natural records,
\nthe variation of the maximum displacement of the base isolation system for a structure with low-height regime
\nand a high-rise structure, design aspects of the
\nbase isolation systems for the two studied structures, remanent displacements of
\nthe base isolation systems and selecting the number of accelerograms to determine the movement of the
\nbase isolation system.<\/p>\n[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none”][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_spacing=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” tablet_text_alignment=”default” phone_text_alignment=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][image_with_animation image_url=”964″ image_size=”full” animation_type=”entrance” animation=”Fade In” hover_animation=”none” alignment=”center” border_radius=”none” box_shadow=”none” image_loading=”default” max_width=”100%” max_width_mobile=”default”][\/vc_column][\/vc_row]\n","protected":false},"excerpt":{"rendered":"
