How to design an elevator system for a 300-story skyscraper?

The peak traffic volume of the hotel occurs during the evening peak hours. At this time, guests mainly go to various restaurants to dine and then return to their rooms. At the same time, guests check in and leave the hotel. The two-way traffic peak needs to be determined according to the functional area of ??the hotel (mainly It is a restaurant) area is quantitatively calculated. Considering that hotel rooms are in high-rise areas, the many elevators in the core tube only go up to the office floor, leaving enough space for hotel elevators. Based on project experience, one elevator can generally serve 60 to 100 guest rooms. Based on this, it is estimated that the hotel will need up to 12 passenger elevators. Based on the actual situation, it is estimated that 8-10 elevators can meet the hotel's requirements.

In addition, due to the nature of the hotel, it is not suitable to use partition settings, because unlike offices, the number of guests staying every day may be different, and the cost of learning the elevator system of the hotel is high. Compared with office buildings, the passenger flow of hotel elevators is much smaller. Usually, a 1.35-ton elevator can meet the actual demand, but many high-end hotels need to use a 1.6-ton elevator. The hotel's sky lobby is set up at high-rise L235, and the shuttle elevator must and can only be used. The shuttle elevator only stops on one floor in the L2~L6 functional area (you need to transfer to other floors, such as escalators) to improve operating efficiency. The fastest elevator in the world is the 18m/s elevator used in Taipei 101 Building. If this type of elevator is used, from L1 on the first floor directly to the sky lobby (height 935m), at least three need to be installed to be closer to hotel standards.

The number of service elevators is generally 50 of the number of passenger elevators. If the number of passenger elevators in this hotel reaches 11, at least 6 service elevators should be installed. A more ideal solution is for two shuttle service elevators to go directly from the underground to the lobby, and four other service elevators to run from the sky lobby through the guest room level to the roof. The podium elevator serves fewer floors and can be diverted by setting up a sufficient number of escalators (the escalator carrying capacity can reach 9,000 people/hour) without further discussion. By the way, usually the elevators in hotels and offices do not leave the garage. Instead, they use the elevator to reach the lobby before entering the guest room or office floor. Judging from the above analysis, the elevators used in hotel rooms can share the same shaft with the office and do not occupy new core space. Therefore, the hotel only needs 3 2 = 5 shuttle elevators. ?
