Structural failure can often produce catastrophic results. In many cases, the damage seen after the accident is not indicative of the cause of the initial failure. Fortunately, based on physical evidence, an investigator can frequently determine how and why a structure failed. The most common reasons for a failure include defective materials, defective design, improper assembly, excessive or improper loading or a combination of these. Through testing and structural analysis, it is possible to determine the root cause of the failure and propose solutions to prevent such failures from reoccurring.
Expertise
We have some 50 years of varied experience in many aspects of structural analysis including:
Structural and mechanical properties testing
Bending, fracture and fatigue analysis
Finite element computer modeling
Teaching structural dynamics at Columbia University, NYU & NASA
In 2011, a 5-year old boy was severely injured at a public playground when he fell through a second floor opening around a fireman's pole in a playhouse. He fell more than seven feet and struck a bare concrete floor. We are thankful that he eventually recovered from his injuries. The person who designed and built the playground was accused of negligence. A lawsuit ensued, and eventually settled in favor of the boy.
A warning must inform individuals of a danger, which would not be obvious to them. It must tell them how to avoid the danger, and be easily understood. It should also provide them with the consequences of not heading the warning.
A person’s interaction with his environment comes largely from visual cues. Without this information, a pedestrian can trip over an unseen object or a driver might not detect a dangerous situation. In order to avoid these hazards, a person requires adequate lighting and should be provided with appropriate illumination for a given task.
