Kindly share your rules of thumb here which are very useful in civil/structural engineering.
The following rules of thumb are useful to me:
1) For every foot span of beam use 3/4 of an inch height for that beam.
2) Size column so that the column area is 0.12% of the area of floor supported.
3) For every story of the building, use 100 mm thickness of raft foundation.
PERFORMANCE BASED SEISMIC AND WIND ENGINEERING FOR 60 STORY TWIN TOWERS IN MANILA
The 14th World Conference on Earthquake Engineering
October 12-17, 2008, Beijing, China
M.R. Willford and R.J. Smith
This paper describes the structural design of two similar 60 storey towers in Manila using performance based
procedures for seismic and wind actions. High-rise buildings designed by performance based methods not only
perform better than conventionally designed ones, but are also less expensive to construct. The buildings
incorporate the Arup Damped Outrigger System, and the savings realized by this are discussed.

I have some towers 30-40m high to design
I would be very grateful to anyone of you who can post a link regarding the design of such towers.
The relevant code of practice for the design is BS 8100

Rules for Member Stability in EN 1993-1-1: Background documentation and design guidelines
ISBN 92914700084
Authors TC 8
Publisher ECCS
Year 2006
Resume:
This volume intends at helping in the understanding of the new design rules for member stability in Eurocode 3 Part 1.1 (EN 1993-1-1:2005). In particular, the new recommendations for lateral torsional buckling and beam-column stability in chapter 6.3.3 (4) of Eurocode 3 are concerned. It is divided into two independent parts A and B.
Part A, devoted to the background of the proposed formulae, gives further information on the way the formulae have been built and validated. Moreover, the different basic concepts used in the formulae are detailed, for the two sets of formulae proposed in the code. It is to be noted that a great number of papers prepared within the development of the formulae are made available by means of a CD-Rom that is part of this publication.
Part B is dedicated to practitioners; it contains fully detailed worked examples on isolated members, from basic situations to the most complex one. In addition, an example of design of a member extracted from a frame is also given. Furthermore an annex shows especially the determination of the elastic lateral torsional buckling moment for different loading and support conditions.
Freeze-Thaw Resistance of Concrete With Marginal Air Content
Author: Jussara Tanesi and Richard Meininger | Size: 2.02 MB | Format:PDF | Publisher: FHWA | Year: 2006 | pages: 96
Freeze-thaw resistance is a key durability factor for concrete pavements. Recommendations for the air void system parameters are normally: 6 ± 1 percent total air, and spacing factor less than 0.20 millimeters. However, it was observed that some concretes that did not possess these commonly accepted thresholds presented good freeze-thaw resistance in laboratory studies. This study evaluated the freeze-thaw resistance of several “marginal” air void mixes, with two different types of air-entraining admixtures (AEA)—a Vinsol resin and a synthetic admixture. This study used rapid cycles of freezing and thawing in plain water, in the absence of deicing salts. For the specific materials and concrete mixture proportions used in this project, the marginal air mixes (concretes with fresh air contents of 3.5 percent or higher) presented an adequate freeze-thaw performance when Vinsol resin based air-entraining admixture was used. The synthetic admixture used in this study did not show the same good performance as the Vinsol resin admixture.
