When lattice shell roofs with a rise are subjected to horizontal ground motions, coupled horizontal and vertical responses are
dominated, and the responses are complicated to estimate. The authors have proposed simple evaluation methods of spherical domes,
cylindrical shells, and freeform lattice shells for computing the responses by use of equivalent static loads. However, these evaluation
methods are examined for shells and domes constituted only by a positive curvature. This paper presents a response evaluation
method of shells with a positive and negative curvature by applying the previously proposed method. This kind of shell is dominated
by two main eigenmodes: bending mode with pin supports, and swaying mode with roller supports. Results of the response evaluation
method using the equivalent static loads are provided by comparing the complete quadratic combination (CQC) method.
