Abstract A procedure is presented for determining the response of a tall building frame to a harmonic motion of the ground. The procedure takes account of the elastic effects of the horizontal beams and requires the use only of a desk computer. Normal modes and natural frequencies can be determined to any desired degree of accuracy by trial and error. Response to any arbitrary motion of the ground can be determined in terms of the responses of the normal modes or, alternatively, by superposing the responses of the complete frame to each harmonic of the motion.

Conti: One of the main conclusions of the Wolf-Rayet symposium in Buenos Aires was that Wolf-Rayet stars are evolutionary products of massive objects. Some questions:–Do hot helium-rich stars, that are not Wolf-Rayet stars, exist?–What about the stability of helium rich stars of large mass? We know a helium rich star of ∼40 MO. Has the stability something to do with the wind?–Ring nebulae and bubbles : this seems to be a much more common phenomenon than we thought of some years age.–What is the origin of the subtypes? This is important to find a possible matching of scenarios to subtypes.
