With over 40 years of experience, Leonard Joseph has analyzed, designed and reviewed high-rise buildings, sports facilities, aircraft hangars, hotels, historic buildings, manufacturing facilities and parking garages. He works with a wide variety of materials, including structural steel, reinforced concrete, precast and post-tensioned concrete, masonry, wood and light-gauge framing.

Len deals with seismic, wind and other environmental hazards on buildings around the world, and he incorporates local construction practices into his designs. His key project credits include the Wilshire Grand Tower in Los Angeles, Shanghai Tower, Taipei 101 in Taiwan, Ping An International Financial Center in Shenzhen and the Petronas Twin Towers in Kuala Lumpur.

Sharing His Technical Expertise
Active in technical development and teaching, he lectures and writes articles and books on structural engineering for both technical and general audiences. He has more than two-dozen technical papers and abstracts to his credit. He co-chaired the Council on Tall Buildings and Urban Habitat’s Outrigger Design Working Group in 2011-2017, developing the first-ever outrigger system design guide. Earlier in his career, he taught steel and concrete structural design courses at New York Institute of Technology.

Outside of Work
For the past dozen years, Len has volunteered with Guide Dogs for the Blind. He and his wife have raised 10 Labradors to date, training each one for 12 to 14 months in preparation for their new roles.
