The rotation of the four floors with respect to a corner point gives rise to an eccentricity between the resultants of the permanent loads for the successive floor levels. The outcome is a torsional load on the load-bearing structure. This torsional load induces horizontal deformations even when the building structure is subjected to vertical loads only. The analysis and the management of these deformations is one of the challenges that we resolved through a 3D structural analysis using Diamonds.<\/p>\n\n\n\n
The O’Sea tower\u2019s rigid central core is of crucial importance in this respect. Starting at the central core, load-bearing concrete walls radiate towards the facade of the building. These walls are rigidly connected to the floor slabs, which provides the torsional rigidity that is needed to resist the torsional load on the building structure. The rigid floor slabs accommodate the horizontal component of the torsional load and transfer the related horizontal loads to the concrete walls and the central core. That makes it possible to design the slanted columns as hinged at both ends. Additional vertical columns are provided where it is necessary to support load-bearing interior walls.<\/p>\n\n\n\n
As mentioned before, the analysis of the horizontal deformations was one of the most important objectives for the 3D structural design analysis using Diamonds. In fact, these analyses confirmed that the permanent loads, self-weight in particular, had by far the most significant impact on the horizontal deformations. Horizontal deformations under the effect of wind loads were found to be even smaller than the horizontal deformations due to the building’s self-weight.”<\/p>\n\n\n\n
Opening up new skylines<\/h2>\n\n\n\n
“Although our project portfolio includes a wide range of building structures, this high-rise building is typical of how we think and work,” Koen Coelus concludes. “Since 1985 I have seen the construction industry change dramatically. It is only by staying alert to these changes that Stedec NV has become what it is today. Opening up new horizons, that’s what matters to us. Or maybe it is more appropriate to say: opening up new skylines?”<\/p>\n","protected":false},"author":6,"template":"","meta":{"_uag_custom_page_level_css":"","site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""}},"_jet_sm_ready_style":"","_jet_sm_style":"","_jet_sm_controls_values":"","_jet_sm_fonts_collection":"","_jet_sm_fonts_links":""},"class_list":["post-3776","reference-project","type-reference-project","status-publish","hentry"],"yoast_head":"\n
