Within the U.S., structural design standards for UHPC have not been fully developed. However, sufficient information exists to carry out conservative designs till refinements are published. For a beam element, service-load flexural design could be performed utilizing linear elastic idea with the related materials properties and with prestress losses assumed to be 10% and 20% at preliminary and last conditions, respectively, and купить тощий бетон с доставкой with tensile stress limit assumed equal to 50% of the flexural energy of UHPC. Prestressing continues to be the primary tension resistance element.
