The impasse was only resolved by Jetty's death from a heart attack in April 1878. Strauss promptly remarried an actress, Angela (Lili) Dietrich, but the age difference (she was 27, he was 52), and his compulsive work patterns soon drove a wedge between them. Frustrated by his long absences and her dull life, she began an affair with theatre director George Steiner, eventually eloping with him.
A composite floor is comprised of a reinforced concrete floor slab and structural steel floor beams acting compositely together. The structure consists mainly of profiled steel decking working together with in-situ reinforced concrete*.
Structural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section. Structural steel shapes, sizes, chemical composition, mechanical properties such as strengths, storage practices, etc., are regulated by standards in most industrialized countries. Most structural steel shapes, such as I-beams, have high second moments of area, which means they are very stiff in respect to their cross-sectional area and thus can support a high load without excessive sagging.
