In the curtain wall design, the need to draw based on stone size, color, materials and other factors of the detailed structural detail, and follow the complete mechanics checking the seismic design codes, compression, and other relevant parameters related nodes to ensure application of stone walls security and stability. General on the stone of choice should be based on the characteristics of the stone walls in indoor and outdoor, in accordance with detail elevation and each node, for its strength, water absorption and vibration levels and other parameters of the mechanical calculations to determine the stone selection, priority should be given characteristic nature stone products, color, texture and other physical properties and, combined with walls of sub-grid form, construction cost, design and layout required to reach the best overall design of the building stone.
In high-rise curtain wall design, for the calculation of the mechanical properties of stone walls associated nodes, we require a combination of structural curtain wall design mode, the connections, material properties and national industry standards of conduct required to complete the calculation of mechanical curtain system. Which can be divided into the following areas:
(1) carry the load is determined. Generally, in determining the load, you need to consider the weight of the stone, wind loads, seismic loads, and other loads forms, maintain effective load transfer structure, for uncertain load, can be determined according to the national standard projections and simulations.
(2) Stone force calculation. Before calculating the stone by force, need to determine the load in the form of stone and stone dry hanging way to determine the model of the stone walls, the stone walls of the load-bearing manner, security, and make calculations. In addition, we also need to make the stress analysis of the stone itself, including the physical properties of stone and indicators, complete the calculation according to the different characteristics of the safety factor of stone.
(3) Stone bending, shear resistance checking. For anisotropic stone, stone walls flexural checking the relevant section can be divided into two cases, one occurred in the largest stone plate bending stress point in the other direction of the stress is zero, as long as the maximum stress is less than in the corresponding direction on Stone allowable stress the stone plate bending performance to meet the requirements of their own, and vice versa is not satisfied. The second is the occurrence of the stone plate in the maximum bending stress point in the other direction is not zero stress, then we must also be considered when checking the stress. Then you can apply the theory of internal friction checking. When checking the shear strength of the stone, we need to be calculated based on the parameter checking the thickness of stone, hole depth.
