The leaning tower of Pisa in Italy, although not intentionally designed, had been a well-known landscape all around the world. Several modern high-rise leaning buildings including Puerta de Europa (Gateway of Europe) in Madrid - the first modern leaning buildings, Barcelona Communication Tower and CCTV New Headquarters have been worked out by contemporary architects and engineers. During the construction of a high-rise leaning building structures, both the P-A effect and geometric nonlinearity must be considered because the continually added gravity loads cause additional bending moment to the structure. The construction of a leaning building structure is a challenging task involving in the determination of pre-set displacement amount as well as implementation of construction schemes. Key issues about construction tracing and simulating analysis of leaning structures are outlined and studied; some helpful conclusions which have been used in CCTV New Headquarters project are presented.
