national Februairtl Kansas City hotel tragedy caused by faulty design United Press International GAITHERSBURG, Md. — Two 32-ton skywalks that col lapsed at the Kansas City Hyatt Regency Hotel last July, killing 113 people, barely were built to support their own weight, gov ernment researchers said today. The National Bureau of Standards said its lengthy inves tigation of the Hyatt Regency tragedy found that the design of the walkways provided for a load tolerance less than that re quired by city building codes. A change during construc tion compounded the problem — doubling the load on the rods suspending the walkways. This left the connection able to sup port just 27 percent of the load standard set by the city, the 349- page NBS report said. “The resultant connection had barely enough capacity to resist the walkway dead load (the weight of the walkway itself) and very little additional capacity to resist the loads imposed by peo- E le,” said Edward Pfrang, who eaded the NBS probe. The NBS investigation did not assess responsibility for the insufficient load capacity that it determined led to structural fai lure as patrons swayed to the strains of “Satin Doll" during a dance in the hotel lobby last July 17. The report said “neither the quality of workmanship nor the materials used in the walkway system played a significant role in initiating the collapse.” In looking for a probable cause, NBS researchers simu lated collapses with skywalk mock-ups and subjected thousands of pounds of steel and concrete debris from the actual walkways to hundreds of tests. Pfrang said it was the NBS’ most extensive investigation ever of a building failure. The original design called for the two walkways to be sus pended from the hotel’s roof by a common set of connection rods. However, the NBS report said a change in construction had the fourth-floor walkway suspended by one set of rods, and the second-floor walkw-ay suspended from the one above it by a second set of rods. “The change in hanger rod arrangement from a continuous rod to interrupted rods essen tially doubled the load to be transferred by the fourth-floor box-beam hanger rod connec tions,” the report said. Pfrang said, “The connec tions as initially detailed and approved for construction pro vided a capacity far below the capacity that would have been required to satisfy the Kansas City Building Code.” The failure to build the sky- walks as designed further aggra vated “an already critical situa tion,” he said. Tons of concrete and steel came crashing down in the hotel lobby when the connection rods running to the roof pulled through the fourth-floor walk way under the excess strain, the NBS report said. The NBS investigation was requested by Kansas City Mayor Richard Berkley, and at last accounting had cost taxpayers $400,000.

Psychiatric attendant jailed in patient ‘hostage’ incident United Press International DAYTON, Ohio — A female mental hospital staff member, allegedly held hostage at gun point by a male patient, was in jail Thursday on charges of sex ual battery and gun smuggling. For nine hours Wednesday, authorities thought Karen Webb, 26, a psychiatric atten dant, was being held hostage by mental patient Donald Bartley, 21, of West Carrollton. But when Bartley, armed with a .25-caliber pistol, surren dered to police negotiators, au thorities began questioning the two and came to a different con clusion. Mendenhall, the facility’s su perintendent, said it appeared that Webb was involved in bring ing the weapon to Bartley. Webb’s husband, also a psychiatric attendant at the hos pital, was “quite upset,” Men denhall said. He said escape or a suicide pact may have been the reason for the incident. While Webb was jailed, Bart ley remained under heavy security at the hospital. He has been a patient since November, 1980, when he was charged with voluntary manslaughter in the shooting death of Frank Abbey of Miamisburg. Bartley, previously ruled in competent to stand trial, recent ly was judged fit for trial, which is scheduled March 8. Mendenhall said Bartley has attempted suicide four times at the hospital and again threatened suicide during Wednesday’s ordeal. United Press International MIAMI — A 36-year-old Dal las pilot imprisoned in Havana’s Combinado del Este prison died last week, apparently electrocut ing himself, the State Depart ment revealed Wednesday. Daerl Gandy, serving a three- year sentence for illegal entry into Cuban territory and one of 13 Americans in the prison, re- K ortedly electrocuted himself in is cell, said Joyce Nichols, the mother of another American prisoner who accompanied Gandy’s wife to Havana the day he died. Gandy’s wife left Havana Sunday, not knowing about her husband’s death. The State De partment notified her Monday. The Miami Herald reported Thursday that the State Depart ment confirmed the death Wednesday but would not say whether the death was a suicide. Gandy’s body will be flown to the United States for burial. Nichols said that Mrs. Gandy, who lives in Dallas, “said she was informed the method of death was self-inflicted electrical shock.” Nichols’ son Neal was jailed with Gandy. He is serving a six-year sentence for illegal en try and marijuana charges. “She told me her husband killed himself over despondancy and depression of having been in jail so long,” said Nichols, who lives in El Paso. Gandy was jailed March 7, 1981 after the Aztec plane he was flying to Mexico from New Orleans ran out of fuel and landed in Cuba. Neal Nichols was co-piloting the plane. “They ran out of fuel and they thought they were in Mex ico, but they were in Cuba,” Nichols said.
