Hospital in Udine

Building use

Hospital

Country/Region

Italy

Overview

The building is the “Laboratory and Analysis” hub of the Udine Hospital. The deep floor plan has two openings in center, creating two vertical voids to provide natural light and ventilation inside the work space. The building perimeter features an external layer of shading elements that protect the interior offices from glare and direct sunlight.

Issue and/or innovation

Composite beams are continuous through the columns.

Reason for composite solution

The composite structure was used to minimize the amount of space take un up by the load bearing elements, both in plan and in height. Columns are only 36x30cm in plan and floors are about 50cm in thickness.

Specific solution/technical details

The structure is composed by a grid of composite columns, formed with a HEB360 profile and 26 Nelson studs on each of the two faces of the web. Concrete is poured on site to achieve a 90m fire rating and to give stability to the profile. Beams are continuous over the columns, and are also formed by HEB360 profile with an additional plate of 10x500mm welded on the bottom flange to support load of the concrete prefab slabs. Composite action on the floor is obtained by means of 100x16mm Nelson studs, welded in two rows every 40cm on both sides of the web along the length of the beam.

Impact or effectiveness

25% time reduction for the creation of the structural frame
Thanks to the composite beams these only occupy 0.25% of the floor plate vs. a 0.8% of conventional concrete columns, equal to a total of 25sqm of additional floor space.
