The invention belongs to the field of building, and particularly relates to a green energy-saving earthquake-resistant building structure. The green energy-saving earthquake-resistant building structure comprises a steel post and a perpendicular line vibration reduction board, and is characterized in that a semicircular vibration reduction board is arranged at the bottom end of the steel post; a plurality of long stayed posts and short stayed posts are connected onto the semicircular vibration reduction board; one end of each long stayed posts is provided with a long stayed post vibration reduction board; one end of each short stayed post is provided with a short stayed post vibration reduction board; a perpendicular line post is also connected onto the steel post; the perpendicular line vibration reduction board is arranged at the bottom end of the perpendicular line post; a transverse board is connected onto the semicircular vibration reduction board; a plurality of steel post reinforced stayed posts are connected onto the transverse board and the steel post; and the steel post reinforced stayed posts and the steel post are connected through transverse board fixing bolts. The green energy-saving earthquake-resistant building structure has the beneficial effects that the structure is simple; the cost is low; the vertical and transverse relative mobility of the perpendicular line post and a foundation post structure is used; and the damage effect of transverse overturning force and drawing force generated by the earthquake on a building structure is enabled to be effectively weakened under the condition of earthquake occurrence..

A method and apparatus for avoiding a short stay problem in a wireless communication system is provided. An eNodeB (eNB) may determine a ratio of a number of short stay user equipments (UEs), which stay at a cell shorter than specific threshold time, to total number of UEs staying at the cell, and transmit the ratio of the number of short stay UEs to the total number of UEs to a previous eNB. Or, the eNB may receive measurement information of at least one second cell from a UE, determine whether the UE can be connected to the at least one second cell, and notify a second eNB whether the UE can be connected to the at least one second cell or not.

The invention relates to a stay cable fundamental natural frequency of vibration measurement method in combination with a sine vibration exciter and a video instrument and belongs to the technical field of civil engineering in order to solve a problem that a conventional measurement means cannot meet a technical requirement for a short stay cable. The method comprises a step a of estimating the range [fD, fU] of the fundamental natural frequency of vibration f1 of a measured stay cable by using a theoretical formula; a step b of installing an exciter at the one-half length of the measured staycable, and installing the video instrument on a fixed floor to observe the vibration displacement at the one-half length a of the measured stay cable and at the quarter length b of the measured staycable; a step c of observing the vibration displacement at the one-half length a of the measured stay cable and at the quarter length b of the measured stay cable by using the video instrument; and astep d of determining the excitation frequency at the moment as the fundamental natural frequency of vibration of the stay cable according to a ratio of the displacements at the two positions. The stay cable fundamental natural frequency of vibration measurement method in combination with the sine vibration exciter and the video instrument can improve the measurement accuracy of the fundamental natural frequency of vibration of the stay cable.
