New Reinforced Concrete Office Towers in New York City

Located at the corner of 42nd Street and 5th Avenue in Manhattan, this office tower is a modern 30-story reinforced concrete building with 550,000 square feet of office space and retail space in the lower seven floors. Designed by Kohn Pederson Fox of New York City, the building architectural features offer stunning views across the street to the New York Public Library and Bryant Park. Early in the design it was decided to keep building columns away from the perimeter and, the main façade was angled to offer unobstructed views of 5th Avenue.

The design team selected an 11- inch-deep conventionally reinforced concrete flat-slab with 22-inch-deep capitals as the most economical floor framing system. This structural design solution offered unrivaled architectural flexibility with spans reaching 45 feet from the curtain wall to the core. More

With the increasing popularity of post-tensioning applications, concrete floor systems are used more frequently now in office buildings throughout the nation. Offering longer spans and lower floor heights, post-tensioned concrete floors are a very attractive option in today’s office construction. By eliminating the cost and time required for fireproofing, cast-in-place concrete construction enhances office building robustness, integrity, and occupant force protection at no additional cost.

Building Green with Concrete

Using concrete can facilitate the process of obtaining LEED™ Green Building certification. Leadership in Energy and Environmental Design (LEED) is a point rating system devised by the United States Green Building Council to evaluate the environmental performance of a building. The system is credit-based, allowing projects to earn points for environmentally friendly actions taken during construction and use of a building. More.

Simplified Design of Reinforced Concrete Buildings

A one-day joint seminar from PCA/ACI to increase your design efficiency and reduce the time it takes to design small to moderate size buildings by applying the design procedures that you will learn at this seminar in accordance with ACI 318-02, IBC 2003, and ASCE 7-02. More.

“….inventors, architects, companies and entrepreneurs (are) trying to recast concrete…as an exciting material with endless decorative and structural possibilities,” reports Ray A. Smith in the July 21 edition of the “Property Report” column from The Wall Street Journal. “On a larger level, post 9/11 national-security concerns have prompted growing use of the material in the form of concrete cores, to enhance stiffness in buildings.”

Liquid Stone: New Architecture in Concrete

The National Building Museum in Washington, D.C., opened a new exhibit celebrating concrete with several special events in June, 2004. The exhibit, Liquid Stone: New Architecture in Concrete, made possible by Lafarge, presents 30 very recent or current projects that use concrete in beautiful and innovative ways. The exhibit will be on view through January 23, 2005. Liquid Stone examines the technology of concrete, its history, and future. More.

Non-Combustible Concrete Construction: Life Safety for Multi-Family Homes

Where There’s Smoke, There’s Fire. And, too often, they result in loss of property, injury, and death. Fires in apartments, condominiums, hotels, motels, dormitories, and assisted living/nursing homes destroy property and disrupt lives.

The non-combustible concrete construction industries have long advocated balanced design for property protection and life safety. Balanced design combines active systems (fire detection and suppression) with passive containment and control through the use of non-combustible fire-resistive walls, floors, and roofs. More.

Concrete Inspection Handbook

Revised! The only handbook on inspection requirements for concrete structures especially written for building officials, plans examiners, and field inspection personnel. It's also a must for those seeking certification as an ICC Reinforced Concrete Special Inspector. Others involved in the designing, specifying, inspecting, and constructing concrete structures will also find the handbook of value. Explains the inspections that are vital to assure compliance with the provisions of ACI 318-02, Building Code Requirements for Structural Concrete, which is referenced in the 2003 editions of the International Building Code and NFPA 5000, Building Construction and Safety Code.
