In order to improve the standardization level of chemical civil engineering design calculation, speed up the design progress and ensure the design quality, the "Format of Masonry Structure Design Calculation Book" (HG21555-93) is specially formulated. This regulation will play a certain guiding role in helping young designers become familiar with design work and master the new specifications. 2. This regulation is applicable to the civil engineering design of common brick masonry structures in the chemical industry, such as the office building in the front area of the factory, the comprehensive building in the chemical plant and various masonry structure calculations. 3. This regulation is compiled in accordance with the following national standards: "Code for Design of Masonry Structures" (GBJ3-88) "Code for Design of Concrete Structures" (GBJ10-89) "Code for Loads on Building Structures" (GBJ9-87) "Code for Seismic Design of Buildings" (GBJ11-89) "Code for Design of Building Foundations" (GBJ7-87) 4. This regulation is used in conjunction with the following two manuals: "Practical Masonry Structure Design Manual", edited by Shi Lanqing (Metallurgical Industry Press) "Reinforced Concrete Component Calculation Manual", edited by Guo Jiwu (Wan Guo Academic Press) 5. This regulation includes the bearing capacity and seismic calculation of masonry structure walls, foundation calculation, and also includes the calculation of various components such as beams, stairs, lintels, and canopies. 6. This regulation organizes and combines the commonly used parameters for masonry structure calculation in the "design data", and the calculation of each part is basically tabulated, which is convenient for review and helps to speed up the design progress. The reinforcement results of commonly used slab stairs, beam pads, and canopies are tabulated in the appendix, which can be directly selected. bzxz.net 7. The examples "Calculation book for five-story masonry structure" and "Canopy calculation" in this regulation are both relatively typical calculation examples, which are specific applications of this regulation. The use of some data is not used as the basis for engineering design. Architectural Design Technology Center of the Ministry of Chemical Industry I. Design Data 1. Design Basis 2.
