8:00 AM - 10:00 AM

Moderators: Stavroula J Pantazopoulou, Kevin R Mackie

Soil Structure interaction effects have been studied through instrumented bridges in the field and through extensive dynamic analyses. It has been illustrated that foundation compliance owing to SSI attenuates seismic demands in monolithic bridge piers but may accentuate seating demands for bearing supports in bridges that are not continuous with the piers. It is the objective of the proposed session to assess the design implications of SSI in controlling the pier/bearing demands as a retrofit measure in existing bridges, as well as to establish a framework for its explicit consideration in new seismic design of bridges, particularly in seismic events of large intensity.
Learning Objectives:
(1) Establish criteria for foundation selection;
(2) Recognize explicitly the role of SSI as a mitigating effect in the bridge system response;
(3) Link pier design strategies to criteria for controlled SSI contribution;
(4) Establish a design framework where SSI is actively used to retrofit existing bridges.

In the past 20 years we have seen an unprecedented rise in the use of concrete for tall buildings, as it has replaced the steel frame as the method of choice. The popularity of concrete is due to several advancements in concrete technology: high strength, self-consolidating concrete, larger concrete pumps, and new structural systems. Presenters will discuss several topics related to concrete materials design and construction issues, as well as mitigation of potential problematic issues such creep and shrinkage, thermal cracking, or delayed ettringite formation.
Learning Objectives:
(1) Identify the top technologies in the industry for concrete construction of tall buildings;
(2) Demonstrate the ways to mitigate thermal cracking and durability issues;
(3) Apply the maturity concept to tall building construction;
(4) Describe the special types of concrete used in tall buildings such as pumpable high strength concrete, SCC, and lightweight concrete.
