About Daniel E. Mariscal

He is a Senior Structural Engineer in the Tampa Office of AECOM (formerly URS). He is involved in preliminary and final bridge design in both steel and concrete. He has been active in several bridge design projects, including segmental concrete structures, steel box girders, and long-span cable-stayed bridges. His technical expertise includes structural analysis and design with an emphasis on computer modeling and diverse computer applications. He is also experienced in time-dependent and linear and non-linear finite element analysis. Typical projects are described below.

 

He was a staff structural engineer for the design on the MIC – Earlington HeightConnector segmental portion, featuring 13 units with a total length of 1.1 miles of constant and variable depth and width precast box girders in Miami, Florida; tenpost-tensioned concrete box girder segmental bridges on the SR 826/SR836Interchange in Miami, Florida; and for the eight segmental bridges on the Big-I Interchange in Albuquerque, New Mexico. The design of these bridges was done, taking into consideration the balance cantilever method of construction. Also, he was involved in the final design of both the steel and concrete alternate for the extradosed stayed-cable bridge on the Pearl Harbor Memorial Bridge in New Haven,Connecticut (I-95 crossing the Quinnipiac River with an estimated cost of$100million).

Expert Tips : Modeling Steel Fracture for Redundancy Analysis Using Detailed Finite Element Method

What is bridge redundancy?

Bridge redundancy is the capacity of the structure to carry loads after the structure is damaged or after one of its members ruptures. The manual for Bridge Evaluation (2008) defines bridge redundancy as the “capacity of the bridge to carry loads after damage or the failure of one or more of its members”. 

Webinar : Redundancy Analysis of twin steel box girder bridges

Demonstrating redundancy for a dual steel box girder system involves in-depth structural analysis and may require enhancements to certain structural details. The benefit is that structures if proven redundant, can be maintained as non-fracture critical. But how to find out if your bridge is redundant or not? Daniel Mariscal will present the Redundancy Evaluation of two twin box flyover structures for the Wisconsin Department of Transportation (WisDOT). He will explain why he selected Midas FEA for this project and how to apply redundancy analysis in Midas FEA.    

Webinar : Refined FEA Analysis : The Pearl Harbor Memorial Bridge (Q Bridge)

The presentation is on the “Pearl Harbor Memorial Bridge (Q-Bridge) – Transverse Design Review and Load Rating”. The Q-Bridge is the first “extradosed” cable-stayed bridge built in the USA. First, the presentation will provide an overview of the project characteristics of the extradosed cable-stayed bridge.
